Abstract
INTRODUCTION: Blindness is a severe debilitating condition to the mankind. Nearly 36 million people are blind all over the world due to various causes. Cataract and uncorrected refractive errors are the most common cause of blindness and severe visual impairment. In India blindness is around 12 million, of which also cataract is the leading cause of preventable blindness that is around 7.75 million. Cataract surgery is one the most frequently performed surgeries throughout the world. In India around 5 million cataract surgeries are performed annually. Manual Small Incision Cataract Surgery (MSICS) and phacoemulsification are the preferred techniques for performing cataract surgeries. AIM OF THE STUDY: To study the corneal endothelial alterations in postoperative MSICS and phacoemulsification in patients visiting PSG Institute of Medical Sciences and Research, Coimbatore. MATERIALS AND METHODS: After clearance from the Institutional Ethical Committee, Patients visiting Ophthalmology OPD for cataract surgery were selected and detailed history was obtained regarding the age, sex, occupation and presenting symptoms, duration, progression and about associated systemic and ocular conditions. Patients were then selected based on inclusion and exclusion criteria. Informed consent was obtained. Preopertaive and postoperative corneal endothelial parameters were noted. The final data was compared with each other. Statistical analysis was done and results were obtained. RESULTS: On comparing preoperative with postoperative CCT values of MSICS and phacoemulsification, there was increase in CCT in both groups in the third post operative week followed by decrease at seven weeks follow up. On comparing MSICS and phacoemulsification the CD values decrease in both the groups postoperatively. And there was an increase in CV values in MSICS compared to phacoemulsification surgeries. CONCLUSION: Our longitudinal comparative study has shown that there is increase in CCT in MSICS compared to phacoemulsification surgeries. The study also showed that there is a significant percentage of cell loss in MSICS compared to phacoemulsification. Polymegethism was noted to be increased in MSICS group than phacoemulsification. Our study demonstrates that phacoemulsification using divide and conquer technique was superior compared to MSICS in terms of postoperative corneal endothelial alterations.
