Incidence and risk factors for vitreous loss in residents performing manual small-incision cataract surgery

AIM: To assess the incidence of vitreous loss and associated risk factors in residents performing manual small-incision cataract surgery(MSICS). METHODS: The present retrospective record review study was performed on 490 patients who underwent MSICS performed between November 2018 and December 2019 by 7 third-year postgraduate residents. The study group comprised of patients having intraoperative vitreous prolapse. All the surgeries were performed under supervision of a trained assistant. RESULTS: The mean age of the participants at the time of surgery was 68.42±2.05 y. Of the 490 patients, 250 patients were male, and 240 patients were female(P=0.23). A total of 215(43.9%) eyes had mature white cataract, 185(37.8%) eyes had brown cataract, and 90(18.3%) eyes had immature senile cataract. The incidence of intraoperative vitreous loss among residents was 2%(10/490). Vitreous loss occurred during hydrodissection [1/10(10%)], nucleus delivery [3/10(30%)], irrigation and aspiration [5/10(50%)], and intraocular lens insertion [1/10(10%)]. Multivariate stepwise Logistic regression analysis confirmed immature senile cataract [odds ratio(OR)=3.99;P=0.02], irrigation and aspiration of cortical material(OR=3.07;P=0.03), and anterior capsular extension(OR=3.22, P=0.03) as independent risk factors for vitreous loss. CONCLUSION: Immature senile cataract, irrigation and aspiration of cortical material, and anterior capsular extension are independent risk factors for vitreous loss. Our findings may serve as a guide for future trainers or residents learning MSICS.

Visual outcome of manual small-incision cataract surgery:comparison of modified Blumenthal and Ruit techniques

AIM:To compare the efficacy and visual results of the modified Blumenthal and Ruit techniques for manual small-incision cataract surgery(MSICS).· METHODS:This was a prospective,non-randomized comparison of 129 patients with senile cataracts scheduled to undergo routine cataract surgery via either a superior scleral tunnel incision,i.e.,the Blumenthal technique(group 1,n = 64) or a temporal scleral tunnel incision,i.e.,the Ruit technique(group 2,n =65).MSICS and intraocular lens implantation were performed through an unsutured 6.5-to 7.0-mm scleral tunnel incision.Uncorrected and corrected visual acuity,intraoperative and postoperative complications,and surgically induced astigmatism calculated by simple subtraction were compared.Patients were examined at 1 day,1 week,1 month,and 3 months after surgery.· RESULTS:Both groups achieved good visual outcome with minor complications.Three months after surgery,the corrected visual acuity was 0.73 in the Blumenthal group and 0.69 in the Ruit group(P =0.29).The average(SD) postoperative astigmatism was 0.87(0.62) diopter(D) for the Blumenthal group and 0.86(0.62) D for the Ruit group.The mean(SD) surgically induced astigmatism was 0.55(0.45) D and 0.50(0.44) D for the Blumenthal and Ruit groups,respectively(P =0.52).Common complications were minimal hyphema and corneal edema.There was no statistically significant difference in the complication rate between the groups(P >0.05).· CONCLUSION:In MSICS,both the Blumenthal and Ruit techniques achieved good visual outcomes,with low complication rates.

Cataract surgery in aged patients:phacoemul-sification or small-incision extracapsular cataract surgery

AIM: To evaluate the effects and safety of phacoemulsification (Phaco) or small-incision extracapsular cataract surgery (SICS) and intraocular lens (IOL) implantation for aged patients. METHODS: Totally 137 aged patients (149 eyes) underwent cataract operation in the case of stable systemic condition, the blood pressure less than 160/95mmHg, blood glucose less than 8mmol/L, and under the help of electrocardiogram surveillance by anesthesiologists during the operation. 106 aged patients (114 eyes) underwent Phaco while 31 aged patients (35 eyes) underwent SICS. The postoperative visual acuity, corneal endothelial cell loss, surgery time and major complications were observed and analyzed retrospectively. RESULTS: The best-corrected visual acuity (BCVA) of >= 0.6 was achieved in 135 eyes (92.6%) at 1 month postoperatively (chi(2)=259.730, P<0.001). For aged patients, both Phaco and SICS could significantly improve visual acuity with no significant difference (chi(2)=4.535, P > 0.05). Postoperative corneal endothelial cell loss was 18.6%, in PHACO group, the rate was 18.5%; in SICS group, the rate was 19.0%, the difference of which was no significant (chi(2)=0.102, P>0.05). The surgery time was different in two groups. No severe complications occurred. CONCLUSION: Both Phaco and SICS combined with IOL implantation for aged patients are effective and safe. Before surgery, detailed physical examination should be performed. When the systemic condition is stable, cataract surgery for aged patients is safe.

Outcomes after combined excisional goniotomy and manual small incision cataract surgery

AIM: To report the long-term outcomes of combined excisional goniotomy and manual small incision cataract surgery(MSICS).METHODS: This is a retrospective case series of patients with open angle glaucoma and visually significant cataracts that underwent combined excisional goniotomy and MSICS with one-year follow-up. The medical history, demographic information, and clinical characteristics of each case were recorded. Data regarding changes in vision, intraocular pressure(IOP), the number of glaucoma medications, and the evolution of the disease after surgery were reported. RESULTS: Three patients, with open angle glaucoma and cataracts underwent combined excisional goniotomy and MSICS without adverse events. All patients had improvement in vision compared to baseline measurements. The range of IOP at baseline was from 14 to 18 mm Hg and decrease to a range of 10 to 14 mm Hg after one year of follow-up. Additionally, two patients also decreased their dependence on IOP-lowering medications at the last follow up visit with one patient maintaining baseline level of medication use.CONCLUSION: A combination of excisional goniotomy and MSICS illustrates both the safety and efficacy to treat patients with visually significant cataract and glaucoma. This procedure allows for a more cost-effective surgical approach that matches the needs of resource strained territories around the globe.

A reasonable option in vitrectomized eyes: manual small incision cataract surgery

Dear Sir,It is known that cataract surgery is challenging in vitrectomized eyes.Cataract surgeons may have encountered with posterior capsular complications and nucleus drop events even with minimal ocular manipulations and low irrigation bottle height.Inadvertent damage to the zonular fibers,posterior or peripheral lens capsule with ocutome or microvitreoretinal(MVR)blade in previous

Incision Site in Manual Small Incision Cataract Surgery in Case of Preoperative Direct Astigmatism

We compared surgically induced astigmatism (SIA) by a superior incision with a temporal incision in manual small incision cataract surgery (MSICS), in patients with bilateral direct (regular) preoperative corneal astigmatisms. Patients and method: We carried out a prospective study from July 1st 2018 to September 30th 2019 in the department of ophthalmology at the University Hospital of Brazzaville. Keratometric readings were recorded before surgery to assess preoperative corneal astigmatisms. Keratometric evaluation was done 45 days post-operatively. Patients were followed 90 days after surgery in order to assess the healing of the surgical site. The surgically induced astigmatism (SIA) is the difference in the magnitude vectors between the preoperative and postoperative astigmatism. The result was positive if the postoperative astigmatism was greater than the preoperative astigmatism and negative if the postoperative astigmatism was less than the preoperative astigmatism. Results: Our study sample included 48 eyes from 24 patients, including 24 operated on temporal incision and 24 in superior incision. The average SIA for superior incisions was 0.33 ± 1.55 diopters (D), versus 0.33 ± 1.44 for temporal incisions. For superior incisions the SIA was 0.81 for astigmatisms lower than 2D, against 0.16D for the temporal incisions. On the other hand, for preoperative astigmatisms greater than 2D, the surgically induced astigmatism was &plusmn;0.62D, marking a decrease in preoperative astigmatism for the superior incisions against an increase of 0.5D for the temporal incisions. The healing was delayed for the temporal incisions responsible for discomfort persisting beyond 45 days. Conclusion: The temporal incision had better results than the superior incision for astigmatisms lower than 2D, and less good for astigmatisms higher than 2D. The temporal incision healed less well.

Assessment of visual outcomes of cataract surgery in Tujia nationality in Xianfeng County, China

AIM: To evaluate the visual outcome and factors influencing visual outcome of manual small incision cataract surgery(MSICS) in the rural area in the Xianfeng County.METHODS: Eighty-two eyes of 82 patients who underwent cataract surgery performed by using MSICS technique were identified. Data collected included each patient’s age, gender, the level of education. Uncorrected and corrected distance visual acuity(UDVA and CDVA) at presentation and at 1, 6, 8wk postoperatively, pre-existing eye disease, operative findings and complications, the risk factors were evaluated.RESULTS: In 82 patients, the average age was 69.6±0.6y, illiterate were 52(63.4%). Of 82 eyes, pseudophakia was present in 77 eyes(93.9%). At 1wk postoperatively,47 eyes(57.3%) had the UDVA of ≥6/18, and 52 eyes(63.4%) had the CDVA of ≥6/18. At 6 to 8wk postoperatively, 50 eyes(61.0%) had UDVA of ≥6/18, and57 eyes(69.5%) had the CDVA of ≥6/18. Postoperative visual status was significantly related to the co-morbidities, such as corneal pathology, glaucoma(P 【0.001).Operative complications, such as posterior capsule opacity and cystoid macular edema were main operative cause for the poor visual outcome.CONCLUSION: MSICS provides a good visual recovery in our study but the vision outcome did not fulfill the standards proposed by WHO, which highlights the need for an improvement in local socioeconomic understanding, population education and surgery quality.

Standard manual capsulorhexis / Ultrasound phacoemulsification compared to femtosecond laser-assisted capsulorhexis and lens fragmentation in clear cornea small incision cataract surgery

Background:Femtosecond-laser assisted clear cornea cataract surgery may hold promise in safer and more effective procedures.We decided to perform a comparative study to standard manual incision phacoemulsification surgery.Methods:This is a single-center,single-intervention,and prospective comparative data evaluation of 133 consecutive cases subjected to cataract surgery.Group-A(Phaco),manual capsulorhexis&ultrasound phacoemulsification(n=66);Group-B femtosecond-laser assisted capsulorhexis and lens fragmentation(n=67),employing the LenSx laser(Alcon Surgical,Ft.Worth,TX).All cases were evaluated for refraction,visual acuity,keratometry,tomography,pachymetry,endothelial cell counts,intraocular pressure,and type of intraocular lens(IOL)implanted.The groups were matched for age,gender,pre-operative vision metrics,and cataract grade,and were followed up to 1 year.Results:In group-A post-operative uncorrected distance visual acuity(UDVA)was 20/20 or better in 61.5%and 20/25 or better in 78.5%of the eyes.The femtosecond laser group-B had improved outcomes(p=0.075 and p=0.042,respectively):post-operative UDVA was 20/20 or better in 62.7%of the eyes and 20/25 or better in 85.1%.Linear regression scatterplots of achieved versus attempted spherical equivalent had excellent regression coefficients(r^(2)=0.983 in group-A and 0.979 in group-B).There were 75.2%cases in group-A and 80.6%in group-B(p=0.8732)within±0.50 D of targeted refractive equivalent.Slight trend of under-correction was noted in group-A.Average residual manifest cylinder in the toric subgroup-A was-0.50 D(95%Limit-of-Agreement(LoA)=-0.78 D),and in toric subgroup-B-0.45 D(LoA=-0.45 D).Conclusions:Mean spherical equivalent refraction and visual acuity are comparable with laser cataract surgery compared with manual capsulorhexis&ultrasound phacoemulsification.Improved astigmatism correction may be among the benefits of femtosecond laser–assisted cataract surgery.Transient corneal edema may be a first day transient disadvantage in femtosecond laser–assisted cataract surgery.
