To evaluate changes in macular thickness via-a-vis visual acuity post uncomplicated manual small incision cataract surgery (MSICS) & phacoemulsification surgery Prospective clinical study on 160 patients of uncomplicated immature senile cataract, aged 40-70yrs, patients were randomised into two groups, MSICS & phacoemulsification, by simple 1:1 randomization, who underwent uncomplicated cataract surgery with posterior chamber intraocular lens (PCIOL). Post-operatively, the patients were evaluated for best corrected visual acuity (BCVA) and changes in macular thickness by optical coherence tomography (OCT) at post-op Day 1, 7, 21, 48, and 12 weeks. Paired t-test was used for comparison across follow up. : At 12 weeks post-operative, mean logMAR BCVA was 0.01±0.02 for MSICS group and 0±0.02 for Phacoemulsification group. Macular thickness was not statistically significant (p=0.342) between MSICS group (219.19±17.88µm) and Phacoemlusification group (215.61±16.21µm), at the end of 12 weeks post-operative. Clinically significant macular oedema was not diagnosed in any of the patients at the follow-ups.: Both procedures achieved good post-operative Best Corrected visual acuity without significant differences in BCVA between both the groups at the end of 12 weeks.

Aim: To assess the complications and visual outcomes associated with cataract surgery in camp patients operated at a tertiary centre. Materials and methods: In a retrospective study, 206 outreach camp patients had undergone cataract surgeries with posterior chamber intraocular lens implantation under peribulbar anesthesia over a period of 6 months. Post-operative complications on Day 1 were graded as per Oxford Cataract Treatment and Evaluation Team (OCTET) definitions. One month postoperative complications, best corrected visual acuity and refractive errors were assessed. Results: 206 eyes underwent cataract extraction with PCIOL implantation. Small incision cataract surgery (SICS) was the commonest method (78.6%) used. The most common first post-operative day complication was mild iridocyclitis (26.2%). The complications were based on OCTET definitions, and showed that 33 % had Grade I and 3.4 % had Grade II complications. The major post-operative complication after 4 weeks of surgery was posterior capsular opacity. 89.8 % of the eyes had a 4 week-post-operative best corrected visual acuity of e” 6/24. The commonest refractive error was myopia with against the rule astigmatism, seen in 86 out of 150 cases. Conclusion: High quality cataract surgery with a low rate of intra-operative complications and good visual outcome can be attained in camp patients operated in the base hospitals, thus justifying more similar screening camps to clear the vast cataract backlog.

Objective To present the surgical outcome of posterior chamber intraocular lens scleral fixation using a 27-gauge trocar-assisted transconjunctival sutureless technique in aphakic patients due to cataract surgery complications with inadequate capsular support. Methods Six consecutive patients with aphakia due to cataract surgery complications with inadequate capsular bag support were operated by two surgeons. Intraocular lens scleral fixation was performed with a 27-gauge trocar-assisted transconjunctival sutureless technique. Patients were followed-up for 12 months. Preoperative and postoperative best-corrected visual acuities were assessed with Early Treatment Diabetic Retinopathy Study charts and expressed in decimals. Results All patients showed statistically significant best-corrected visual acuity improvement and excellent anatomic results. Mean preoperative best-corrected visual acuity was 0.17 (range of 0.1–0.2). Mean postoperative best-corrected visual acuity was 0.84 (range of 0.63–1.00). Mean initial spherical equivalent refractive error was +11.85 (range of +9.00 to +15.00). Mean final spherical equivalent refractive error was –0.25 (range of –1.25 to +2.25). There were no postoperative complications during the whole follow-up. Conclusion Fixation of a posterior chamber intraocular lens using a 27-gauge trocar-assisted transconjunctival sutureless intrascleral technique is an excellent option for aphakic patients secondary to cataract surgery complications with inadequate capsular support.

Objective- To evaluate and compare efficacy and safety of topical Difluprednate ophthalmic emulsion 0.05% with Nepafenac ophthalmic suspension 0.1% in patients of uneventful cataract surgery with respect to postoperative macular thickness and volume. Design- A prospective, single centric, tertiary care centre based, comparative, interventional study from August 2013 to July 2014 Subjects- Total 206 ( Group N=106, Group D=100) patients were followed up who completed their 12 weeks follow up Methodology- Surgery was performed by phacoemulsification technique by clear corneal incision with foldable PCIOL implantation by a single surgeon having 10 years of surgical experience. Post operative patients were divided into 2 groups. Group N were given topical treatment with Nepafenac ophthalmic suspension  0.1% TID starting 24 hours before surgery  and continued post-op 4 weeks. Group D were given Difluprednate ophthalmic emulsion 0.05% QID post surgery for 2 weeks followed by BID for 2 weeks.  Main outcome measures: Postoperative assessment of patients were done on 1st day and on 1st, 8th and12th  weeks  after the surgery for best corrected visual acuity (BCVA) by logMAR, intraocular pressure by Applanation tonometry and macular thickness and volume by SD-OCT. Statistical test used was sample Unpaired and paired ‘t’ test  and statistical analysis was done with SPSS 20.0 ( IBM, USA). Results- There was increase in the measured mean central subfield thickness( CST) at 8 and 12 weeks as compared to 1 week , in both the study groups (P<0.05). On comparing the volume (in mm3) and average thickness (in µm) at 1 week, it was observed that thickness of group N (266.82±25.06 µm) was statistically higher than that of group D (253.14±22.21µm) (P= 0.03). The comparison of best corrected visual acuity (LogMAR) and the intraocular pressure recordings showed no difference between the patients of two studied groups recorded at 1 week and 8 weeks and 12weeks. Conclusion- Both Nepafenac ophthalmic suspension 0.1% and Difluprednate ophthalmic emulsion 0.05% are equally effective in controlling macular thickness change after uneventful cataract surgery.

To study "small incision cataract surgery (SICS)" for the rehabilitation of cataract visually impaired and blind patients, a retrospective study of 100 cases of cataract patients with small incision cataract surgery (SICS) with posterior chamber intraocular lens (PCIOL) implantation were done at Rajshahi Medical College Hospital. All cases were selected having corrected visual acuity less than 6/60 who were admitted at the Department of Ophthalmology for cataract surgery from March, 2006 to February, 2008. Age group of the patient range from 40 to 85 years. Age related senile cataract were selected any complicated cataract was excluded from the study. All these patients underwent SICS with 5.5 mm optic polymethylmethacrylate (PMMA) non-foldable posterior chamber intraocular lens (PCIOL) were implanted by irrigation vectis. Intra operative complication were present in 8% cases among them 3 cases (3%) required to conversion to Conventional Extracapsular Cataract Extraction (ECCE). 2 cases (2%) had small posterior capsular rent (PCR), 1 case (1%) irido dialysis & 2 cases (2%) hyphaema occurred. Postoperative complications were found in 38 cases (38%) among them transient corneal oedema occurred in 18 cases (18%) iritis occurred in 13 cases (13%), decentering of intraocular lens (IOL) occurred in 2 cases, corrected visual acuity after 6 weeks of operation were 6/12 or better in 97 cases (97% cases achieved functional vision). Induced astigmatism ± 0.50 D to ± 1.00 D occurred in 94 cases (94%) and ± 1.500 to 2.50D in 6 cases (6%). So, SICS may be the choice of surgery in respect of visual outcome with the limited facilities and surgeons. DOI: 10.3329/taj.v22i1.5037 TAJ 2009; 22(1): 132-135

Purpose: To present the technique and outcomes of a modified manual small incision cataract surgery designed for the phacoemulsification surgeons who are learning to perform manual small incision cataract surgery. Methods: This was a retrospective, single-centred, comparative study. We included all the patients who underwent the modified manual small incision cataract surgery for visually significant cataract at Singapore National Eye Centre. All surgeries were performed by either a senior phaco-trained surgeon (M.A.) who had performed more than 500 manual small incision cataract surgery or a junior phaco-trained surgeon (D.C.) who had performed around 500 phacoemulsification but never performed any manual small incision cataract surgery. The main modification of this technique lies in the creation of an additional phaco-like main wound at 90° to the scleral tunnel wound, with most surgical steps performed through this additional wound. The outcomes were analysed and compared between the senior and junior surgeons. The main outcome measures were visual outcome and major intraoperative complications such as posterior capsular rupture and zonular dialysis. Results: A total of 132 cases were included; 102 (77.3%) and 30 (22.7%) cases were performed by the senior and junior surgeons, respectively. Pre-operatively, 85.6% eyes had best-corrected visual acuity of counting fingers or worse. Postoperatively, the visual outcome at 1 month was similar between the senior and junior surgeons, with 68.7% eyes achieving a best-corrected visual acuity of ⩾6/12 ( p = 0.17). No posterior capsular rupture, zonular dialysis or endophthalmitis was observed during the study period. Conclusions: This modified technique may serve as a useful transition technique for the phaco-trained surgeons to develop skills in manual small incision cataract surgery, with demonstrable good visual outcome and safety.

Introduction: In manual, tunnel-incision cataract surgery, nucleus extraction has remained a crucial issue and a challenge. It is also the period when serious complications easily occur, especially for beginners and when the nucleus is large and dense.  Objectives: To report a modified vectis technique for nucleus extraction in sutureless, manual, small-incision cataract surgery (MSICS) to improve the safety and ease of performance.Materials and methods: A novel nucleus extraction technique using a vectis in MSICS is presented. After capsulorhexis and hydrodissection, the nucleus is moved into the anterior chamber and extracted by pulling with a Sinskey hook and pressuring on the scleral bed near the posterior wound margin with an irrigating vectis. Main outcome measures: The operating time for the whole surgery and nucleus extraction, best corrected visual acuity postoperatively and complications during and after operation were recorded. Results: In a series of 1,180 eyes, the operating time for the whole surgery and nucleus extraction were 8±3.4 minutes and 5.1±4.6 seconds respectively. Among all the eyes, 88.98 % achieved a best-corrected visual acuity of 5/10 or better two months postoperatively. The complications were posterior capsule rupture (4 eyes, 0.34 %) and transient corneal edema (12 eyes, 1.02 %). Neither vitreous loss nor dislocation of the nucleus into the vitreous was noted in the whole series of the surgery. Conclusions: We found that the “scleral bed” vectis technique for nucleus extraction improved the ease of performance, safety of MSICS, and did not require expensive instrumentation.DOI: http://dx.doi.org/10.3126/nepjoph.v6i2.11708Nepal J Ophthalmol 2014; 6 (12): 140-144

Currently, posterior chamber intraocular lenses (IOLs) correct totally or partially spherical aberrations. In this article we present the visual results of a prospective multicentre study evaluating the Micro AY IOL correcting 0.11μm of spherical aberration, which is a good compromise between optimal vision and a consistent depth of focus. We evaluated 124 eyes that were operated on using bi-manual micro-cataract surgery (BiMICS: 75%) or co-axial micro-cataract surgery (CoMICS: 25%) phacoemulsification with insertion of a Micro AY IOL through a 1.8–2.2mm incision. Mean post-operative best corrected visual acuity was 0.97±0.25; pre-operative spherical aberrations were +0.24±0.13μm, and reached +0.10±0.11μm post-operatively. There were no complications due to the lens, and photopic contrast sensitivity reached high levels.
