A Clinical Analysis of 120 Cases with Traumatic Cataract Treated by Extracapsular Cataract Extraction and Posterior Chamber Intraocular Lens Implantation

Extracapsular cataract extraction was performed combined with posterior chamber intraocular lens implantation on 120 inpatients (122 eyes) with traumatic cataract from 1992 to 1997. The results revealed that this combined operation can make most of them get useful visual acuity, although they were often accompanied with several comlicated eye injuries. We think the most important thing is to choose suitable opertion time, the reasonable operation method and take close followup after operation.

Clinical Effect Analysis of Posterior Chamber Intraocular Lens Implantation for Correcting High Myopia and Astigmatism

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.

Posterior chamber phakic intraocular lens implantation for high myopia

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.

Visual performance after implantation of two types of phakic foldable intraocular lenses for correction of high myopia

AIM: To compare Visian lens(model V4 c) and Artiflex lens regarding quality(contrast sensitivity) and quantity(efficacy, predictability, safety and stability) of vision in correcting high myopia with recording and analysis of complications. METHODS: The comparative prospective study included 39 eyes of 23 patients with high myopia, 19 eyes had Visian lens implantation(model V4 c) and 20 eyes had Artiflex lens implantation. The inclusion criteria were high myopia(higher than 6.0 D) and stable refraction(<0.5 D change over one year). Outcomes included assessment of safety and efficacy indices, predictability, stability, contrast sensitivity and analysis of complications at postoperative 1 d, 1 wk and 1, 3, 6 and 12 mo. Selection of the type of phakic intraocular lens for patients was based on surgeons' preferences, which was no specific selection criteria. RESULTS: After 12 mo of follow up, difference in uncorrected and corrected distant visual acuity(CDVA) between both groups was statistically insignificant(UDVA for VisianV4 c and Artiflex lens were 0.33±0.2 logMAR and 0.37±0.2 logMAR respectively, P=0.59, CDVA for VisianV4 c and Artiflex lens were 0.155±0.1 logMAR and 0.147± 0.1 logMAR respectively, P=0.87). The efficacy index was 1.25 for VisianV4 c lens and 0.8 for Artiflex lens, 78.9% of eyes were within one diopter spherical equivalent in Visian V4 c lens group compared to 70% in the Artiflex lens group. No eye lost lines of CVDA proving a good safety index for both lenses(safety index was 1.67 for VisianV4 c lens and 1.34 for Artiflex lens). Difference in contrast sensitivity between both groups was statistically insignificant(P=0.15, 0.88, 0.27, 0.32 and 0.82 at five spatial frequencies). CONCLUSION: Both Visian ICL V4 c and Artiflex lensesare safe and effective with stable and predictable refraction and they have comparable contrast sensitivity outcomes with no vision threatening complications.

Outcomes of secondary sulcus intraocular lens implantation in unilateral anterior persistent fetal vasculature

AIM: To evaluate the surgical results of sulcus intraocular lens(IOL) implantation in children with unilateral anterior persistent fetal vasculature(PFV) underwent primary vitrectomy combined with lensectomy and preservation of the peripheral anterior capsule.METHODS: Twenty-two eyes of 22 children with unilateral anterior PFV who underwent sulcus secondary IOL implantation were analyzed. Main outcome measures were preoperative and postoperative visual acuity, and complications both intraoperatively and postoperatively. RESULTS: Review of 22 consecutive patients identified best-corrected visual acuity(BCVA) improvement from 1.37±0.84 to 0.73±0.57 logarithm of the minimal angle of resolution(logMAR) after IOL implantation(P<0.001) with a mean follow-up was 16.55±5.86 mo. Average age at secondary IOL implantation was 41.05±15.41 mo. Three eyes(13.64%) achieved BCVA of 0.3 logMAR at the final visit. Transient intraocular pressure rise(4 eyes; 18.18%), postoperative increased inflammation(3 eyes; 13.64%) and postoperative hypotony(2 eyes; 9.09%) were common complications.CONCLUSION: Properly preservation of the anterior lens capsule during the primary surgery facilitated secondary sulcus IOL implantation in pediatric patients with anterior PFV, with favorable postoperative visual outcomes and compatible percentage of complications.

Diffractive multifocal intraocular lens implantation in patients with monofocal intraocular lens in the contralateral eye

AIM:To evaluate clinical outcomes of unilateral implantation of a diffractive multifocal intraocular lens(IOL)in patients with contralateral monofocal IOL.METHODS:Twenty-two patients who already had implantation of a monofocal IOL in unilateral eye underwent implantation of a diffractive multifocal IOL in contralateral eye were enrolled.After 1,6,and 12 mo,uncorrected and distant corrected distant visual acuity(UCDVA and DCDVA),uncorrected and distant corrected intermediate-visual acuity(UCIVA and DCIVA),uncorrected and distant corrected near visual acuity(UCNVA and DCNVA),and contrast sensitivity were obtained.Halo/glare symptoms,spectacle dependence,and patient satisfaction were also evaluated.RESULTS:The mean age was 67.86±7.25 y and the average interval between two IOL implantations was 645.82±878.44 d.At 1 mo,binocular UCDVA was lower than 0.20 logMAR in 76%of patients(mean 0.12±0.13 logMAR),which increased to 90%by 6 and 12 mo.The binocular UCDVA was significantly better than the monocular results(P<0.05)at 1,6,and 12 mo.Additionally,UCNVA was lower than 0.40 logMAR in 82%of patients,increasing to 90%by 6 and 12 mo.Mean UCNVA in the multifocal IOL implanted eye was statistically significantly better than that in the monofocal IOL implanted eye(P<0.05)at 1,6,and 12 mo.About 5%of patients at 1 and 6 mo,reported"severe glare or halo".Patient satisfaction rates were 95%and 91%at 6 and 12 mo,respectively.CONCLUSION:Unilateral implantation of multifocal IOL in patients with a contralateral,monofocal IOL implantation results in high patient satisfaction rate,with low severe glare or halo rate during follow-up.It can represent a good option for patients who have previously had a monofocal IOL implantation regardless of two year interval duration between two IOL implantations.

Flapless one-knot suture:a novel surgical technique for transscleral fixation of C-loop intraocular lenses

AIM:To describe a novel suture approach for transscleral fixation of C-loop intraocular lenses(IOL)and to compare the surgical outcomes with the four-haptics posterior chamber(PC)-IOL technique.METHODS:We retrospectively analyzed 16 eyes of 16 patients who underwent transscleral fixation of C-loop PCIOLs using a flapless one-knot suture technique,which were followed up for longer than 17mo.In this technique,the capsulorless IOL was suspended using a single suture for transscleral fixation of four feet.Then we compared its surgical outcomes and complications with the four-haptics PC-IOLs using the Student's t test and Chi-square test.RESULTS:Sixteen patients of 16 eyes with a mean age of 58.3±10.1y(42-76y)who received transscleral C-loop IOL implantation due to trauma,vitrectomy,or cataract surgery with inadequate capsule support showed improved visual acuity.The difference was not significant between two IOLs except the surgery time(P>0.05).The mean operation times of C-loop IOL surgery was 24.1±1.83min and 31.3±4.47min of the four-haptics PC-IOL method(P<0.0001).In the C-loop IOLs group,there was statistical difference between the preoperative and the postoperative UCVA(log MAR,1.20±0.50 vs 0.57±0.32,P=0.0003).There was no statistical difference between the preoperative and the postoperative BCVA(log MAR,0.66±0.46 vs 0.40±0.23,P=0.056).However,there was no statistically significant difference in postoperative UCVA and BCVA between the two IOLs(P>0.05).We did not detect any optic capture,IOL decentration or dislocation,suture exposed,or cystoid macular edema in patients underwent C-loop IOLs surgery.CONCLUSION:The novel flapless one-knot suture technique for transscleral fixation of C-loop IOL is a simple,reliable,and stable technique.

Evaluation of suturless scleral fixation with posterior chamber foldable intraocular lens implantation

AIM: To assess the sutureless scleral fixation technique for posterior chamber foldable intraocular lens(PCIOL) implantation in aphakic eyes with insufficient or no capsular support. METHODS: A technique for sutureless intrascleral fixation of the haptics of a standard 3-piece PCIOL was used which ensures sutureless fixation by permanent incarceration of the haptics in a scleral tunnel parallel to the limbus. All patients were evaluated for preoperative status [visual acuity, refractive error, K readings, intraocular pressure(IOP) measurement, slit lamp examination, fundus examination and optical biometry], postoperative status and complications. Ultrasound biomicroscopy(UBM) was done for 10 cases to evaluate optic tilt. RESULTS: The study evaluated 42 eyes of 42 patients. The follow-up period was 6 mo. Improvement of best corrected visual acuity(BCVA) one line occurred in 10 cases(23.8%) and loss of one line in 3 cases(7.1%). Intraoperative complications included: haptic kink in 4 cases(9.5%), haptic breakage in 1 case(2.4%), haptic dislocation in 1 case(2.4%), haptic slippage in 3 cases(7.1%), IOL dislocation in 1 case(2.4%) and sclerotomy related bleeding in 1 case(2.4%). Postoperative complications included: transient mild vitreous hemorrhage in 3 cases(7.1%), choroidal detachment in 1 case(2.4%), cystoid macular edema(CME) in 1 case(2.4%), optic capture in 1 case(2.4%), subconjunctival haptic in 2 cases(4.8%), ocular hypotony in 4 cases(9.5%) and ocular hypertension in 1 case(2.4%). There were no cases of retinal detachment or endophthalmitis. UBM showed optic tilt in 3 cases(30%). CONCLUSION: Fixation of three-piece foldable IOL haptics in scleral tunnel parallel to the limbus-providedaxial stability and proper centration of the IOL with minimal or no tilt in most cases and a low complication rate during the follow up period which lasted 6 mo.

Trocar opening: silicone oil removal with phacoemulsification and intraocular lens implantation

AIM: To evaluate the efficacy and safety of a modified technique [trocar opening(TO)] for silicone oil removal(SOR) in combination with phacoemulsification and intraocular lens(IOL) implantation.METHODS: A total of 60 eyes of 60 patients with cataract and silicone oil-filled eyes were enrolled in this study. The patients were divided into two groups: the patients in the control group underwent 23-gauge pars plana active SOR surgery with phacoemulsification and IOL implantation, while the patients in the TO group underwent TO methods during surgery. Best corrected visual acuity(BCVA), surgery time, intraocular pressure, and operative complications were observed 6 mo after surgery.RESULTS: There was no significant difference between the two groups in terms of age, gender, preoperative, intraocular pressure, or time of silicone oil stay. Prior to surgery, the mean BCVA for the control and TO groups was 1.34±0.44 and 1.36±0.42. At 6 mo following surgery, the mean BCVA improved to 0.74±0.36 and 0.77±0.32, respectively(P<0.001). There was no significant difference between the two groups. The mean SOR time was 6.9±2.3 min and 4.8±1.2 min in the control and TO groups(P=0.008). The total operation time was 28.2±8.5 min and 24.6±6.4 min, respectively(P=0.035). Posterior capsule rupture occurred in four eyes of control and none of TO group(P<0.01). Late recurrent retinal detachment occurred in one eye in the control group(2 mo after surgery) and in one eye in the TO group(4 mo after surgery). CONCLUSION: TO is a simple, effective, time-saving, and safe method for SOR combined with phacoemulsification and IOL implantation.

Commentary review:challenges of intraocular lens implantation for congenital cataract infants

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.

Using Topical Anesthesia for Standing Phacoemulsification Cataract Surgery and Intraocular Lens Implantation

Introduction: To report by using topical anesthesia for standing phacoemulsification and intraocular lens implantation for two patients who need cataract extraction but unable to lie flat with marked cervical kyphosis due to long-standing ankylosing spondylitis and chronic uveitis. Methods: Two patients are unable to lie flat respectively during phacoemulsification underwent this technique in Jingdong and Tonghai county Hospital of Yunnan province in China. Each patient was positioned erect or semirecumbent in a standard reclining cataract surgical chair. The ceiling-mounted microscope was rotated 60 degrees from the vertical to point toward the patient. Results: The intraoperative and postoperative periods were uneventful in two patients, with good visual outcomes after surgery. Conclusion: This technique is valuable for situations where the patient requires upright positioning because of the inability to recline flat, and should be considered for cases where standard surgical positioning is not possible.

Bimanual microincision cataract surgery with implantation of the new Incise~? MJ14 intraocular lens through a 1.4 mm incision

AIM：To analyze the visual outcomes and the posterior capsule opacification（PCO）with the new Incise？MJ14intraocular lens（IOL）implanted through a 1.4 mm clear corneal incision（CCI）in patients who underwent bimanual microincision cataract surgery（B-MICS）.METHODS：Eighty eyes which underwent cataract surgery using B-MICS technique performed by the same experienced surgeon were included in the study：40 eyes were implanted with an Incise？MJ14 IOL through a 1.4 mm CCI（group A）without enlargement of the main CCI,while 40 eyes were implanted with an Akreos？MI60 IOL with enlargement of the main CCI to 1.8 mm（group B）.Best corrected visual acuity（BCVA）,astigmatism and endothelial cell loss were evaluated before and after surgery at 7,30d and 6mo.Anterior segment-optical coherence tomography（AS-OCT）of CCI was performed at 1,3,7,30d,6 and 18mo.PCO incidence was evaluated at 18mo using EPCO 2000 Software.RESULTS：Mean BCVA improvement and endothelial cell loss were statistically significant at 18mo in both groups with no difference between the two groups;no statistically significant difference in surgically induced astigmatism（SIA）was noticed in the two groups.At AS-OCT the only significant alterations in the CCI were endothelial gaping and local detachment of Descemet’s membrane at 1 and 7d after surgery;no statistically significant alterations were found at 1,6 and 18mo.PCO score at 18mo was 0.03±0.07for group A and 0.08±0.18 for group B（P=0.11）with no sign of central optic plate invasion in both groups.CONCLUSION：The implant of the new Incise？MJ14 IOL through a 1.4 mm CCI and B-MICS technique appeared to be a safe and effective procedure with rapid visual recovery.PCO rate resulted very low and the CCI presented few morphological alterations which were only detectable in the first days postoperatively and achieved fast corneal healing during the long-term follow-up.

The morphological changes of cellson the surface of F-heparin surface modified intraocularlenses after implantation in the rabbits’eyes

After intraocular implantation of F ion-heparin surface modified intraocular lenses(FHSM IOLs) in the rabbits’eyes,there were small cells on the surfaces of IOLs accompanied by fibrinous exudates in the early days.The cells included macrophages,fibroblast like cells,epithelioid cells,small foreign body giant cells and lymphocytes.As time went on it showed increasing variation of cell size and fusion of cells.At last the surface of IOLs were covered by a thin and transparent membrane chiefly made by degenerated cells and fibrins,and then the IOLs were well tolerated in the eyes.

Early clinical outcome with lens position adjustment following implantable collamer lens surgery

AIM:To observe early clinical outcome with lens position adjustment following the implantable collamer lens(ICL)surgery.METHODS:Sixty patients were selected for this retrospective study.One eye from each patient received Toric ICL for astigmatism correction,and the other received non-astigmatic ICL surgery using horizontal position.Patients with higher postoperative arch height were selected,and their non-astigmatic eye clinical outcome were observed after ICL surgery at 1wk,1,and 3mo.The clinical measurements included uncorrected visual acuity(UCVA),intraocular pressure(IOP),refractive state,corneal endothelium cell count,and arch height.Three months later,the ICL in each patient’s non-astigmatic eye was adjusted to the vertical from the horizontal position.The results were compared before and 1wk,1,and 3mo after adjustment.RESULTS:UCVA and IOP were significantly reduced 1wk after position adjustment compared to 1wk after ICL implantation(P<0.05).The patients demonstrated significantly reduced arch height and corneal endothelium cell count 1wk,1,and 3mo after adjusting position compared to 1wk,1,and 3mo after ICL implantation(P<0.05).However,there was no significant difference in refraction between 1wk,1,and 3mo after ICL implantation and position adjustment(P>0.05).CONCLUSION:Early positioning adjustment postphakic ICL implantation can benefit patients with adjusted arch height or higher IOP.Despite the good clinical effects,the doctors should pay attention to the potential for adverse effects on UCVA and corneal endothelium cells following early position adjustment after posterior chamber phakic ICL implantation.

Effects of Intraocular Lens Implantation without Viscoelastic Agents on Corneal Endothelial Cells

Objective: To determine the protective effects of intraocular lens implantation without viscoelastic agents on corneal endothelial cells. Methods: Patients with age-related cataract were randomly divided into two groups: Group A (24 patients, 30 eyes) underwent phacoemulsification and intraocular lens implantation without viscoelastic agents, and group B (21 patients, 30 eyes) underwent phacoemulsification and intraocular lens implantation with viscoelastic agents. The corneal endothelial cell counts, percentages of hexagonal cells, and central corneal thicknesses were evaluated at 1 week, 1 month, and 6 months after surgery. Results: There was no significant difference in preoperative basic characteristics between the two groups (p > 0.05). The postoperative corneal endothelial cell count and percentage of hexagonal cells in both groups decreased compared with preoperative values at 1 week, 1 month, and 6 months after surgery, and the decrease of group A was significantly lower than that of group B at all time points (p p > 0.05). Conclusions: Compared with regular intraocular lens implantation, intraocular lens implantation without viscoelastic agents is less damaging to corneal endothelial cells, resulting in greater corneal safety.
