Main outcomes evaluated at 3mo of follow-up, included uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), residual refractive cylinder and intraocular lens(IOL) axis rotation.Objective optical quality were measured using optical quality analysis system(OQAS Ⅱ, Visiometrics, Spain),included the cutoff frequency of modulation transfer function(MTFcutoff), objective scattering index(OSI),Strehl ratio, optical quality analysis system value(OV)100%, OV 20% and OV 9% [the optical quality analysis system(OQAS) values at contrasts of 100%, 20%, and 9%].RESULTS: At 3mo postoperative, the mean UDVA and CDVA was 0.18 ±0.11 and 0.07 ±0.08 log MAR; the mean residual refractive cylinder was 0.50 ±0.29 D; the mean toric IOL axis rotation was 3.62 ±1.76 degrees, the mean MTFcutoff, OSI, Strehl ratio, OV 100%, OV 20% and OV9% were 22.862 ±5.584, 1.80 ±0.84, 0.155 ±0.038, 0.76 ±0.18,0.77±0.19 and 0.78±0.21. The values of UDVA, CDVA, IOL axis rotation, MTFcutoff, OSI, Strehl ratio, OV100%,OV20% and OV9% depending on the power of the cylinder of the implantation were not significantly different(P 】0.05), except the residual refractive cylinder(P 【0.05).CONCLUSION: The optical quality analysis system was useful for characterizing the optical quality of Acry Sof toric IOL implantation. Implantation of an Acry Sof toric IOL is an effective and safe method to correct corneal astigmatism during cataract surgery.展开更多

One group(55 patients) had preoperative marking of both eyes done with bubble marker(ASICO AE-2791TBL) and the other group(55 patients) with pendulum marker(Rumex 誖 3-193). Reference marks were placed at 3-, 6-, and 9-o'clock positions on the limbus. Slit-lamp photographs were analyzed using Adobe Photoshop(version 7.0). Amount of alignment error(in degrees) induced in each group was measured.· RESULTS: Mean absolute rotation error in the preoperative marking in the horizontal axis was 2.42±1.71 in the bubble marker group and 2.83 ±2.31 in the pendulum marker group(P =0.501). Sixty percent of the pendulum group and 70% of the bubble group had rotation error ≤3(P =0.589), and 90% eyes of the pendulum group and 96.7% of the bubble group had rotation error ≤5(P =0.612).·CONCLUSION: Both preoperative marking techniques result in approximately 3 of alignment error. Both marking techniques are simple, predictable, reproducible and easy to perform.展开更多

Patients are classified into 2 groups considering the incision type: cornea group with patients undergone clear corneal incision; sclera group with patients undergone sclera tunnel incision. All patients with postoperative astigmatism of under 1 diopter (D) were included to minimize the effect of residual astigmatism on postoperative HOAs. Visual acuity, special equivalents, astigmatism, predictability (±1 D from target refraction), HOAs (coma, trefoil, spherical aberration), and corneal endothelial counts were analyzed preoperatively and 6mo postoperatively.RESULTS: At the postoperative 6mo, all patients of both groups achieved uncorrected visual acuity of 16/20 or better, and significantly decreased the spherical equivalents compared with preoperative values. The predictability of refractive correction was 96% in the former, and 94% in the latter. Unlike the sclera group, preoperative astigmatism decreased significantly in cornea group at postoperative 6mo. The HOAs increased significantly at postoperative 6mo compared to the preoperative values in both groups, and the root mean square (RMS) total and trefoil wavefront aberration of cornea group were significantly higher than those of sclera group.CONCLUSION: Although corneal incision significantly reduces preexisting astigmatism, the postoperative 6mo of total RMS and trefoil aberration change may deteriorate the visual quality after Artisan PIOL implantation.展开更多

METHOD...AIM:To evaluate the long-term outcome of implantation of black diaphragm intraocular (BDI) lens combined with penetrating keratoplasty (PKP) for managing aphakic eyes with traumatic aniridia and corneal damage. METHODS: Six aphakic eyes of six patients with traumatic aniridia and corneal damage had BDI lens implantation at Qingdao Eye Hospital, Shandong Eye Institute from June 2008 to November 2011. Medical records of the patients were reviewed. Three patients received PKP and after 12-18months were implanted with BDI lens. The other three patients completed PKP and BDI lens implantation at the same time. The corrected visual acuity, intraocular pressure and number of corneal endothelial cells were monitored. RESULTS: The patients were followed up for an average of 24.3 ±12.1months (range 14-48 months). All BDI lenses were located well. The best corrected visual acuity got improved in 5 patients (0.1-1.0) and decreased in 1 patient from 0.4 to 0.2. Three patients had normal intraocular pressure (IOP) after implantation. Two patients required antiglaucoma medications to control IOP within the normal range and 1 patient implanted Ahmed glaucoma valve to control IOP. The corneal grafts kept transparent in all eyes and the corneal endothelial counting 】1 000/mm2 , although two patients experienced acute graft rejection and loss more than 30% corneal endothelial cells.CONCLUSION: Implantation of BDI lens combined with PKP is an effective option for managing aphakic eyes with traumatic aniridia and corneal damage. Although the results in our study are encouraging, additional studies of the long -term safety and efficacy are required. Alarger study population and longer follow-up may be beneficial.展开更多

The preoperative refraction values were +17.75DS -1.50DC × 168° for the right eye and +17.25DS -0.75DC × 8° for the left eye. The uncorrected visual acuity (UCVA) was 20/200 bilaterally and the spectacle-corrected visual acuity (BSCVA) was 20/50 bilaterally. One year after Artisan iris-fixated IOL implantation, bilateral BSCVA was 20/50 with a refraction of +1.25DS -0.75DC × 13° for the right eye and +1.50DS -1.00DC × 55° for the left eye. The outcomes of an Artisan iris-fixated IOL implantation followed to CLE with PC-IOL implantation were encouraging for the correction of extreme hyperopia. Long term follow-up examinations were necessary for further determination of the efficacy and safety of this combinational procedure.展开更多
文摘Objective:To explore the corrective effect of posterior chamber intraocular lens implantation with phakic eyes in the treatment of high myopia and astigmatism.Methods:From May 2023,the hospital began to collect the case data of diagnosis and treatment of high myopia and astigmatism.By May 2024,310 cases were included,all of which were treated with posterior chamber intraocular lens implantation.The visual acuity,astigmatism and axial position of the intraocular lens were observed before and after treatment.Results:At different time points after the operation,the patient’s vision was significantly improved compared with that before the operation(P<0.05),and the vision level was equal to or greater than the best-corrected vision before the operation.At different time points after the operation,the average rotation of the intraocular lens was less than 5 degrees.Astigmatism was significantly lower than that before the operation(P<0.05).After the operation,the intraocular pressure increased in 11 cases,accounting for 3.55%,with no adverse complications such as lens turbidity,glare and obvious halo occurring.Conclusion:The posterior chamber intraocular lens implantation with phakic eyes has an ideal correction effect in the treatment of high myopia and astigmatism,which can effectively improve the vision level of patients and reduce the degree of astigmatism,and has high effectiveness and safety.
文摘AIM:To evaluate the efficacy,safety and stability of posterior chamber phakic intraocular lens implantation for the correction of high myopia.METHODS:Retrospective case review of 82 eyes(43patients)undergoing implantable Coliamer lens(ICL)placement by a single surgeon(Xiao-Wei Gao)to correct preoperative mean spherical equivalents between-9.00diopter(D)and-23.00D.Main outcome measures included uncorrected visual acuity(UCVA),refraction,best spectacle-corrected visual acuity(BSCVA),endothelial cell density(ECD),intraocular pressure(IOP),lens transparency,postoperative uveitis.Visante anterior segment optical coherence tomography(AS-OCT)was used to measure anterior chamber depth(ACD)and the position of ICL.RESULTS:Mean follow-up was 6.54±3.26 months(range 3-12 months).Predictability of the manifest spherical equivalent(SE)refraction to within±1.OOD was achieved in 88%of eyes and±0.50D in 72.5%of eyes.The mean postoperative manifest SE refraction was-1.85±0.72D,with 96.34%of eyes maintaining or gaining≥1 line(s)of BSCVA.The mean 3-month postoperative ECD decreased but had no statistically difference compared with the preoperative ECD.Of the 7 eyes(8.54%)with a mild transient increase in intraocular pressure(up to 30mmHg),none required a second surgical procedure or prolonged topical medication.There was no loss of lens transparency.Pigmented precipitates were observed in 5 eyes(6.09%).The mean preoperative ACD measured with AS-OCT was 3.28±0.14mm,three months after surgery,the mean ACD was2.45±0.22mm.Anterior chamber depth showed astatistically significant reduction.One eye(1.22%)had ICL spontaneous rotation,81 eyes(98.78%)of the lens remained correctly centered.CONCLUSION:The implantation of ICL is an effective surgical option for the management of high myopia.But its long time effect and safety still need more time to prove.
文摘AIM:To investigate and compare the quality of life,satisfaction,contrast sensitivity,glare,depth perception,and intraocular lens(IOL)rotation in patients who underwent trifocal toric and bifocal toric IOLs.METHODS:A total of 80 eyes of 40 patients were included in this prospective study.Twenty patients in each group were implanted with trifocal toric and bifocal toric IOL,respectively.Preoperative and postoperative 6-month measurements were recorded for both patient groups.Comprehensive anterior and posterior segment examinations,distance-intermediate-near visual acuity values and the visual function scale questionnaire results were evaluated at these examinations.Patient satisfaction,contrast sensitivity,glare,intermediate-near and distance stereopsis and IOL rotation were also evaluated.RESULTS:No significant difference was found between the groups in terms of distance and near visual acuities(P=0.269,P=0.451).Intermediate visual acuity was significantly increased in the trifocal toric group(P<0.001).The visual function scale results were increased after surgery in both groups(P=0.001 and P<0.001),with no difference determined between them(P=0.158 and P=0.691).The number of patients wearing glasses was low in both groups and there was no significant difference between the groups(P>0.05).The overall satisfaction in the trifocal toric group was significantly higher than in the bifocal toric group(P=0.03).The highest sensitivity was observed at 6 cpd spatial frequency in all patients under photopic conditions(1.80±0.24 logU,1.74±0.20 logU).Distance-intermediate-near binocular depth perception results in both groups were higher in the trifocal toric group(P=0.02,0.048,0.003,respectively).Although there was no significant difference for 3 meters stereopsis,the trifocal toric group had higher depth perception(P=0.577).Mean rotation was 5.76°±3.93°in the trifocal toric group and 12°±7.1°in the bifocal toric group.CONCLUSION:Better results in the middle distance are obtained in the trifocal toric group and less IOL rotation due to digital system-coordinated surgery.Moreover,the overall satisfaction in the trifocal toric group is significantly higher than in the bifocal toric group.

文摘Background:Femtosecond laser astigmatic keratotomy(FSAK)and toric intraocular lens(IOL)implantation have been studied individually for comparison to treat astigmatism at cataract surgery.We report a case of surgically induced high corneal astigmatism by laser thermal keratoplasty(LTK)in a patient with cataract who was successfully treated with simultaneous combination of FSAK and toric IOL implantation with femtosecond laser-assisted cataract surgery(FLACS).This is the first report of both procedures combined simultaneously,with or without history of LTK.Case Description:A 68-year-old male presented with a history of LTK with two enhancements each eye in 2004,with subsequent surgically induced high corneal astigmatism,and with age-related nuclear cataract of both eyes.IOL master demonstrated+7.71 diopters of astigmatism at 163 degree right eye and+3.29 diopters of astigmatism at 4 degree left eye.After extensive discussion of the risks and benefits,the patient agreed to undergo FLACS with FSAK with two 61 degrees of relaxation incisions(RIs)and toric IOL(Alcon SN6AT9)right eye;FLACS with toric IOL(Alcon SN6AT7)alone left eye.At 2-year follow-up,uncorrected visual acuity was 20/30 right eye,20/25 left eye.His best corrected visual acuity was 20/25(+0.25+1.00 axis 21)right eye and 20/20(plano+0.25 axis 90)left eye;his best corrected near visual acuity was J1+with add+2.50 diopters right eye and left eye.Conclusions:Patients with age-related cataract and LTK induced high corneal astigmatism can hardly be sufficiently treated with FSAK or toric IOL alone at the time of cataract surgery.An effective way is to combine large FSAK and toric IOL of the highest cylindrical power of T9,in our case,simultaneously,which can achieve an excellent long term visual outcome.
文摘AIM: To investigate the independent factors associated with photic phenomena in patients implanted with refractive,rotationally asymmetric,multifocal intraocular lenses(MIOLs).METHODS: Thirty-four eyes of 34 patients who underwent unilateral cataract surgery,followed by implantation of rotationally asymmetric MIOLs were included.Distance and near visual acuity outcomes,intraocular aberrations,preferred reading distances,preoperative and postoperative refractive errors,mesopic and photopic pupil diameters,and the mesopic and photopic kappa angles were assessed.Patients were also administered a satisfaction survey.Photic phenomena were graded by questionnaire.Independent-related factors were identified by correlation and bivariate logistic regression analyses.RESULTS: The distance from the photopic to the mesopic pupil center(pupil center shift) was significantly associated with glare/halo symptoms [odds ratio(OR)=2.065,95% confidence interval(CI)=0.916-4.679,P=0.006] and night vision problems(OR=1.832,95% CI=0.721-2.158,P=0.007).The preoperative photopic angle kappa was significantly associated with glare/halo symptoms(OR=2.155,95% CI=1.065-4.362,P=0.041).The photopic angle kappa was also significantly associated with glare/halo symptoms(OR=2.155,95% CI=1.065-4.362,P=0.041) and with night vision problems(OR=1.832,95% CI=0.721-2.158,P=0.007) in patients implanted with rotationally asymmetric MIOLs.CONCLUSION: A large pupil center shift and misalignment between the visual and pupillary axis(angle kappa)may play a role in the occurrence of photic phenomena after implantation of rotationally asymmetric MIOLs.
文摘AIM: To analyze the optical quality after implantation of toric intraocular lens with optical quality analysis system.METHODS: Fifty-two eyes of forty-four patients with regular corneal astigmatism of at least 1.00 D underwent implantation of Acry Sof toric intraocular lens, including T3 group 19 eyes, T4 group 18 eyes, T5 group 10 eyes,T6 group 5 eyes. Main outcomes evaluated at 3mo of follow-up, included uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), residual refractive cylinder and intraocular lens(IOL) axis rotation.Objective optical quality were measured using optical quality analysis system(OQAS Ⅱ, Visiometrics, Spain),included the cutoff frequency of modulation transfer function(MTFcutoff), objective scattering index(OSI),Strehl ratio, optical quality analysis system value(OV)100%, OV 20% and OV 9% [the optical quality analysis system(OQAS) values at contrasts of 100%, 20%, and 9%].RESULTS: At 3mo postoperative, the mean UDVA and CDVA was 0.18 ±0.11 and 0.07 ±0.08 log MAR; the mean residual refractive cylinder was 0.50 ±0.29 D; the mean toric IOL axis rotation was 3.62 ±1.76 degrees, the mean MTFcutoff, OSI, Strehl ratio, OV 100%, OV 20% and OV9% were 22.862 ±5.584, 1.80 ±0.84, 0.155 ±0.038, 0.76 ±0.18,0.77±0.19 and 0.78±0.21. The values of UDVA, CDVA, IOL axis rotation, MTFcutoff, OSI, Strehl ratio, OV100%,OV20% and OV9% depending on the power of the cylinder of the implantation were not significantly different(P 】0.05), except the residual refractive cylinder(P 【0.05).CONCLUSION: The optical quality analysis system was useful for characterizing the optical quality of Acry Sof toric IOL implantation. Implantation of an Acry Sof toric IOL is an effective and safe method to correct corneal astigmatism during cataract surgery.
文摘AIM:To compare the efficacy and complications of Artisan iris-claw intraocular lens(IOL)implantation and posterior chamber IOL sulcus fixation for the treatment of aphakic eyes without capsular support after vitrectomy.METHODS:A prospective study of 45 cases was conducted.Forty-five eyes without sufficient lens capsule support following pars plana vitrectomy(PPV)combined lens extraction were divided into two groups.Group A:25 eyes received Artisan iris-claw IOL implantation.Group B:20 eyes received posterior chamber IOL sulcus fixation.The corrected distance visual acuity(CDVA)and intraocular pressure(IOP),corneal endothelial cell loss rate,surgical time and complications were compared between the two groups.Pigment changes of trabecular meshwork and anterior chamber depths were measured at each time point in Artisan group.RESULTS:The mean surgical time of Artisan group was significantly shorter(P【0.05).No statistically significant difference in endothelial cell loss rate was noted between two groups at any time point(P】0.05).CDVA of Artian group was better than that of the sulcus fixation group 1d after surgery(P【0.05)and there was no statistically significant difference 1 and 3mo after surgery(P】0.05).Mean IOP showed no significant differences between groups before and after surgery.The postoperative complications of Artisan group were anterior uveitis,iris depigmentation,pupillary distortion and spontaneous lens dislocation.The complications of sulcus fixation group include choroidal detachment,intraocular haemorrhage,tilt of IOL optic part and retinal detachment.CONCLUSION:Secondary Artisan IOL implantation canbe performed less invasively and in a shorter surgical time period with earlier visual recovery after surgery compared to transscleral suturing fixation of an IOL.This technique is an effective and safe procedure.It is a promising option for the treatment of aphakic eyes without capsular support after vitrectomy.

文摘AIM: To compare the accuracy of two different methods of preoperative marking for toric intraocular lens(IOL) implantation, bubble marker versus pendulum marker, as a means of establishing the reference point for the final alignment of the toric IOL to achieve an outcome as close as possible to emmetropia.·METHODS: Toric IOLs were implanted in 180 eyes of110 patients. One group(55 patients) had preoperative marking of both eyes done with bubble marker(ASICO AE-2791TBL) and the other group(55 patients) with pendulum marker(Rumex 誖 3-193). Reference marks were placed at 3-, 6-, and 9-o'clock positions on the limbus. Slit-lamp photographs were analyzed using Adobe Photoshop(version 7.0). Amount of alignment error(in degrees) induced in each group was measured.· RESULTS: Mean absolute rotation error in the preoperative marking in the horizontal axis was 2.42±1.71 in the bubble marker group and 2.83 ±2.31 in the pendulum marker group(P =0.501). Sixty percent of the pendulum group and 70% of the bubble group had rotation error ≤3(P =0.589), and 90% eyes of the pendulum group and 96.7% of the bubble group had rotation error ≤5(P =0.612).·CONCLUSION: Both preoperative marking techniques result in approximately 3 of alignment error. Both marking techniques are simple, predictable, reproducible and easy to perform.
文摘This cohort study included 36 eyes of 21 patients with high myopia treated with angle supported phakic intraocular lens(p IOL).Endothelial cell density(ECD) at baseline,6 mo and 3 y were 3017±296,2775±265 and 2558±299 cells/mm^2 respectively.ECD loss at 6 mo was 7.2% and annual ECD loss was 3% over 36 mo.Corrected distance visual acuity at 36 mo was 0.4 log MAR or better in 32(88.9%) eyes.Intraocular pressure did not change(P=0.9).No eyes developed cataract,retinal detachment or pupillary distortion.Angle supported p IOL gives good visual outcome.Endothelial cell loss should be monitored.
文摘AIM: To evaluate the effect of incision types for Artisan phakic intraocular lens (PIOL) implantation on ocular higher-order aberrations (HOAs).METHODS: A retrospective review was conducted of the patients who had undergone Artisan PIOL implantation for the correction of myopia and followed up for at least 6mo. Patients are classified into 2 groups considering the incision type: cornea group with patients undergone clear corneal incision; sclera group with patients undergone sclera tunnel incision. All patients with postoperative astigmatism of under 1 diopter (D) were included to minimize the effect of residual astigmatism on postoperative HOAs. Visual acuity, special equivalents, astigmatism, predictability (±1 D from target refraction), HOAs (coma, trefoil, spherical aberration), and corneal endothelial counts were analyzed preoperatively and 6mo postoperatively.RESULTS: At the postoperative 6mo, all patients of both groups achieved uncorrected visual acuity of 16/20 or better, and significantly decreased the spherical equivalents compared with preoperative values. The predictability of refractive correction was 96% in the former, and 94% in the latter. Unlike the sclera group, preoperative astigmatism decreased significantly in cornea group at postoperative 6mo. The HOAs increased significantly at postoperative 6mo compared to the preoperative values in both groups, and the root mean square (RMS) total and trefoil wavefront aberration of cornea group were significantly higher than those of sclera group.CONCLUSION: Although corneal incision significantly reduces preexisting astigmatism, the postoperative 6mo of total RMS and trefoil aberration change may deteriorate the visual quality after Artisan PIOL implantation.

文摘As an indispensable part of congenital cataract surgery,intraocular lens(IOL)implantation in infantile patients has long-term positive impacts on visual rehabilitation,as well as postoperative complications inevitably.Timing of IOL implantation in infantile congenital cataract patients is not simply a point-in-time but a personalized decision that comprehensively takes age at surgery,risks of postoperative complications,and economic condition of family in consideration,and combines with choosing suitable IOL type and power.For infants with well-developed eyeballs and good systemic conditions,IOL implantation at six months of age or older is safe and effective.Otherwise,secondary IOL implantation may be a safer choice.
文摘AIM:To evaluate the safety and efficacy of scleral-fixated 3-looped haptics intraocular lens(IOL)implantation for surgical management of microspherophakia.METHODS:A retrospective case series include 10 microspherophakic patients(15 eyes)who underwent lens removal plus a modified surgical treatment of scleral-fixated 3-looped haptics IOL implantation.The primary outcomes involved visual acuity,intraocular pressure(IOP).Secondary outcomes were spherical equivalent(SE),anterior chamber depth(ACD),corneal endothelial cell density and postoperative complications.RESULTS:After a postoperative follow-up of 17.60±15.44mo,improved visual outcomes can be observed.The uncorrected distance visual acuity(UCVA)log MAR improved from 1.54±0.59 preoperatively to 0.51±0.35 postoperatively(P=0.001),and best corrected visual acuity(BCVA)log MAR improved from 0.97±0.91 preoperatively to 0.24±0.23 postoperatively(P=0.003).Moreover,the SE decreased from-9.58±7.47D preoperatively to-0.65±2.21 D postoperatively(P<0.001).In terms of safety profile,the average IOP decreased from 21.10±12.94 mm Hg preoperatively to 14.03±3.57 mm Hg postoperatively(P=0.044),and the previously elevated IOP of three eyes decreased to the normal range.The ACD increased from 2.25±1.45 mm preoperatively to 3.35±0.39 mm postoperatively(P=0.017).The density of corneal endothelial cells did not change significantly after surgery(P=0.140).The posterior chamber IOLs were well centered and no severe complications were found.CONCLUSION:Lens removal plus the modified surgical treatment of scleral-fixated 3-looped haptics IOL implantation can help in improvement of visual acuity,which can be regarded as a relative safe method for the surgical management of microspherophakia.
文摘AIM:To evaluate the long-term outcome of implantation of black diaphragm intraocular (BDI) lens combined with penetrating keratoplasty (PKP) for managing aphakic eyes with traumatic aniridia and corneal damage. METHODS: Six aphakic eyes of six patients with traumatic aniridia and corneal damage had BDI lens implantation at Qingdao Eye Hospital, Shandong Eye Institute from June 2008 to November 2011. Medical records of the patients were reviewed. Three patients received PKP and after 12-18months were implanted with BDI lens. The other three patients completed PKP and BDI lens implantation at the same time. The corrected visual acuity, intraocular pressure and number of corneal endothelial cells were monitored. RESULTS: The patients were followed up for an average of 24.3 ±12.1months (range 14-48 months). All BDI lenses were located well. The best corrected visual acuity got improved in 5 patients (0.1-1.0) and decreased in 1 patient from 0.4 to 0.2. Three patients had normal intraocular pressure (IOP) after implantation. Two patients required antiglaucoma medications to control IOP within the normal range and 1 patient implanted Ahmed glaucoma valve to control IOP. The corneal grafts kept transparent in all eyes and the corneal endothelial counting 】1 000/mm2 , although two patients experienced acute graft rejection and loss more than 30% corneal endothelial cells.CONCLUSION: Implantation of BDI lens combined with PKP is an effective option for managing aphakic eyes with traumatic aniridia and corneal damage. Although the results in our study are encouraging, additional studies of the long -term safety and efficacy are required. Alarger study population and longer follow-up may be beneficial.

文摘A 22-year-old patient suffering from both-side extreme hyperopia with amblyopia was corrected with an Artisan iris-fixated intraocular lens (IOL) implantation followed to clear lens extraction (CLE) with posterior chamber (PC)-IOL implantation. The preoperative refraction values were +17.75DS -1.50DC × 168° for the right eye and +17.25DS -0.75DC × 8° for the left eye. The uncorrected visual acuity (UCVA) was 20/200 bilaterally and the spectacle-corrected visual acuity (BSCVA) was 20/50 bilaterally. One year after Artisan iris-fixated IOL implantation, bilateral BSCVA was 20/50 with a refraction of +1.25DS -0.75DC × 13° for the right eye and +1.50DS -1.00DC × 55° for the left eye. The outcomes of an Artisan iris-fixated IOL implantation followed to CLE with PC-IOL implantation were encouraging for the correction of extreme hyperopia. Long term follow-up examinations were necessary for further determination of the efficacy and safety of this combinational procedure.
