Purpose: The main purpose of this study was to compare the macular thickness after uncomplicated Phacoemulsification versus manual SICS in known diabetic patient by OCT.
Methods: This study was prospective observational study involving 50 eyes of 50 patients with each arm having 25 patients. Group 1 was operated with Phacoemulsification with foldable IOL through 2.2 mm incision & group 2 were operated with manual SICS through 5.5 to 6.5 mm incision with PMMA IOL implantation. Macular OCT was performed in all patients during preoperative period & day 7 post op, 1st month, 3rd month & 6th month. The data were analyzed by using SPSS software (version22.0 SPSS Inc).
Results: The MCFT rose steadily in both group during post operative period with higher rise noted in SICS group throughout follow up. Significant difference in MCFT between Phaco & SICS group were noted with highest MCFT noted in 1st month follow up in both groups i.e. 231.6 micro m (SD+7.831) in Phaco group & 241.08 (SD+7.35) in SICS group. The MCFT returned to near pre OP value by 6th month.
Conclusion: 1 Age & Sex has no effect on macular thickness before and after any type of Cataract surgery be it Phaco or SICS.
2 Significant higher macular thickness was observed in SICS group so caution should be taken in SICS patients.
