“…Analysis of PHACO and SICS procedure on senile cataract showed that the macular thickness was higher in SICS group. 24 The authors showed significant difference in macular thickness between PHACO and SICS group on 3rd day, 7th day, 3rd month and 6 months follow up. 24 The results of our study were similar to that analysis, though their study was on senile cataract and ours was on adolescent patients.…”

Purpose: This study analyzed macular thickness (FMT) and retinal nerve fiber layer thickness (RNFL) following phaco-aspiration (PHACO) and small incision cataract surgery (SICS) in adolescent eyes. Methods: Macular thickness and RNFL thickness were measured using optical coherence tomography (OCT) in 52 eyes who underwent PHACO or SICS surgery. OCT measurements were done preoperatively, and on 1st, 14th, 42nd, 84th and 168th postoperative days. Eyes with any other diseases were excluded. Paired sample t-test was used to compare the parameters. Results: The FMT and RNFL thicknesses were found to be higher postoperatively. The SICS group had significantly higher macular thickness (233.06 ± 31.23 μm) than the PHACO group (227.33 ± 28.25 μm) on the 42nd day. The RNFL thickness in SICS was significantly higher than in PHACO and highest on the 84th postoperative day, with mean average value 95.04 ± 16.61 μm and 91.98 ± 18.22 μm respectively. Conclusions: This study shows that cataract surgery increases the macular and RNFL thickness. These increases are significantly higher in the SICS than in PHACO eyes on the 42nd day after surgery, which resolves gradually towards 168th day after surgery. This indicates that phaco aspiration is more preferable surgery then SICS in adolescents with regard to postoperative increase in macular and RNFL thickness.

“…Many authors showed significant difference in macular thickness between PHACO and SICS group on 3 rd day, 7 th day, 3 rd month and 6 months post-operative follow ups. 9 A study done by Dr. Indranil Roy et al on total 224 patients who were randomised to two groups-phaco and SICS, found mean central foveal thickness in SICS group was more than that of phaco group on post-op 1 st , 7 th , 42 nd and 180 th day. On day 180, mean central foveal thickness in SICS group was significantly (p=0.032) more than phaco group.…”

To study the relationship between HbA1c and macular thickness using Optical coherence tomography (OCT) in phacoemulsification and SICS. Retrospective study where 100 eyes of type 2 Diabetes mellitus patients with mild to moderate Non-Proliferative Diabetic Retinopathy (NPDR) were included. 50 PATIENTS underwent uncomplicated phacoemulsification surgery AND REST 50 FOR SICS and were divided into 3 groups based on HbA1c levels – Group 1: <6.5%, Group 2: 6.5%–8% and group 3: >8%. Nine macular subfields as defined by Early Treatment of Diabetic Retinopathy study (ETDRS) were measured using OCT. The HbA1c level of each patient was measured and compared with the macular thickness as well as visual acuity. The macular thickness was found to be significantly higher postoperatively in SICS group (251.54 ± 22.69 μm) than the PHACO group (230.44 ± 26.47 μm) on post-operative day 7 and it further increased to (267.46 ± 43.44 μm) in SICS group as compared to phaco group (244.50 ± 37.30 μm)on postoperative 1 month in group C. CMT was highest if HbA1C levels were more than 8% as compared to other two groups on all post-operative day.No significant difference was found in BCVA between both the groups on 1 month and 3 months post-operatively. This study shows that cataract surgery increases the macular thickness and these increases are significantly higher in the SICS than in PHACO eyes on the POD 7, 1 month and 3 months after surgery, especially if HbA1c levels are more than 6.5%, which resolves to near normal levels in phaco group by POD 3 months. This indicates that phacoemulsification is more preferable surgery then SICS in adults with regard to postoperative increase in macular thickness. Also good control of HbA1c levels significantly decreases post-operative visual problems.

Background: The main aim of the study is to compare the change in macular thickness after uncomplicated phacoemulsification versus uncomplicated manual SICS in known diabetic patients by optical coherence tomography Methods: This study was an observational study involving 50 patients with each group having 25 patients. Group 1 was operated with Phacoemulsification through limbal 2.8 mm incision with Foldable PCIOL implantation. & Manual small incision cataract surgery through 5.5 to 6.5 mm incision with sclerocorneal tunnel with PMMA PCIOL implantation. For all patients, macular OCT was performed during preoperative period & post-op 1st day,7th day, 1st month, 3rd month & 6th month. Statistical software SPSS, version 21.0 was used for statistical analysis. Results: In both PHACO & SICS group MCFT rose steadily during post-operative period and SICS group shows high rise during follow up.The MCFT shows a difference between PHACO & SICS group with the highest MCFT observed in 1st month follow up i.e., 231.6 micrometer (SD ±7.831) in PHACO group & 241.64 (SD ±7.35) micrometer in SICS group. The MCFT returned to near pre-op value by the 6th month. Conclusion: There is no effect of age and sex on macular thickness before and after in both PHACO and SICS groups. In SICS group significant macular thickness was observed as compared to PHACO group, so there should be more cautious to undertake SICS in those patients who are at risk of developing macular edema or who have a higher macular thickness as seen in diabetes patients. Keywords: Phacoemulsification (PHACO), small incision cataract surgery (SICS), Cystoid macular edema.
