A New Technique

Purpose To describe a new technique to split rock-hard nuclei using an ultrasonic chopper (Ultrachopper) and a prechopper, in order to perform a modified small incision manual cataract extraction. Methods The Ultrachopper device, which is compatible with modern phacoemulsification systems, is used to facilitate the division of very hard nuclei in a straightforward manner using a manual prechopper, and the two fragments are extracted using Kansas forceps. Results In rock-hard nuclei, this technique is very effective to divide and extract the fragments. The risk of complications related to phacoemulsification on these very challenging cases is avoided. Conclusions This modified small incision manual cataract extraction technique, assisted with an ultrasonic chopper (Ultrachopper) and a prechopper, is a very good alternative in rock-hard nuclei.

Background: An effective method for cataract surgery should be identified to combat cataract blindness. Aim: To study the surgical outcome of conventional extracapsular cataract extraction versus manual small-incision cataract surgery. Materials and methods: A randomized clinical trial was carried out including one hundred eyes (88 patients) which were divided into two groups using systematic randomization: groups of conventional extracapsular cataract extraction with posterior chamber intraocular lens (ECCE with PCIOL) implantation and manual small-incision cataract surgery (MSICS). The postoperative parameters/variables studied were the unaided and best-corrected visual acuity and astigmatism. Statistics: Epi info 2000 version statistical software was used for data analysis and calculation of relative risk, 95% CI and p value. The p value of less than 0.05 was considered as significant. Results: In the immediate postoperative period, unaided visual acuity of =/> 6/18 was achieved in 24 subjects in MSICS group versus 7 in ECCE with PCIOL group (RR=2.05, 95% CI=1.44 - 2.94, p = 0.0002), whereas the same at 6 - 8 weeks postoperatively was found in 28 and 22 subjects in those groups respectively (RR=1.27, 95% CI=0.86-1.89, p=0.23). The astigmatism of =/> 2 at 6 - 8 weeks was found in 35 and 17 subjects from the conventional and MSICS groups respectively ( R=2.28, 95% CI = 1.39-3.73, p=0.0002). Conclusion: Both MSICS and conventional ECCE with PCIOL are safe and effective techniques for treatment of cataract patients. A more rapid recovery of good vision can be achieved with MSICS than with conventional ECCE with PCIOL in the immediate postoperative period.

Introduction: The small-incision cataract surgery is gaining popularity among the ophthalmic surgeons. Objective: To compare the visual outcome of conventional extra-capsular cataract extraction (ECCE) and small-incision cataract surgery (SICS) in a hospital based community cataract program. Materials and methods: A prospective interventional study without randomization was carried out including the patients undergoing cataract surgery by either conventional ECCE or manual SICS. They were followed up for 6 weeks postoperatively. The visual outcomes were compared between the two groups. Statistics: The statistical program Epi-Info version 2000 was used to analyze the data. Mean values with standard deviations, 95% CI and p value were calculated. The p value of <0.05 was considered significant. Results: Of 85 patients, 44 (M: F=10:34) underwent ECCE and 41 (M: F=15:26) SICS (RR= 0.71, 95% CI=0.42-1.2, p value=0.16). Unaided visual acuity on the 1st postoperative day in the ECCE group was e"6/ 18 in 22.7%,<6/18-6/60 in 63.6 %,< 6/60 in 13.7%, whereas in the SICS group, the same was e"6/18 in 70.7%,<6/18-6/60 in 22 %,< 6/60 in 7.3% (95% CI = 0.23 - 0.48, p=0.001). Best corrected visual acuity on the 6th week follow-up in the ECCE group was e"6/18 in 79.5%,<6/18-6/60 in 18.2 %,< 6/60 in 2.3% and in the SICS group the same was 6/18 in 90.5% and <6/18-6/60 in 4.9% (95% CI=0.44 - 0.73; p=0.0012). Conclusion: Both ECCE and SICS are good procedures for hospital based community cataract surgery but within the 6 weeks postoperative period SICS gives better visual outcome. Remarkably higher number of female patients can be provided service in a hospital based community cataract programme as compared to males.

Purpose:  To use clinical audit in improving the outcomes of manual small incision cataract surgery technique Study Design:  Clinical audit. Place and Duration:  Layton Rehmatullah Benevolent Trust Eye hospital Karachi, from September 2019 to December 2019. Methods:  Two hundred patients who had undergone Manual Small Incision Cataract surgery were selected. Cases with traumatic cataract, weak zonules, pseudoexfoliation, and more than 1 diopter difference in keratometric readings, corneal and retinal pathologies were excluded. Surgical complications and visual outcomes were recorded on the 7th postoperative day. Refractive data was recorded from subjective refraction. Data was analyzed by University Hospital Bristol formula. Standards were set using international literature. Deficiencies were noted and technique was modified to improve the outcome. The audit was repeated after 2 months to see whether modifications had improved the outcome. Results:  In the first audit, posterior capsular rupture rate was 1%, corrected visual acuity of 6/12 or better was achieved in 85.36% and surgically induced cylinder of less than 2 DC was achieved in 75.60% of the patients. In the second audit all standards were achieved. Posterior capsular rupture did not occur. Corrected visual acuity of 6/12 or better was achieved in 90.50% and induced cylinder of less than 2 DC was achieved in 87.05% of the patients. Conclusion:  Clinical audit of the surgical procedures is a good technique in improving the outcomes of manual small incision cataract surgery. Key Words:  Cataract extraction, clinical audit, posterior capsular rupture, astigmatism, visual acuity.
