A Study to Compare the Endothelial Cell Loss in Different Techniques of Cataract Surgery

To compare the endothelial cell loss in different technique of cataract Surgery.

A Prospective study, included 100 cataract cases in the Age group of 50–75 yrs was conducted between Aug 2009 to Sept 2011 at Navodaya Medical College and Research Centre, Raichur. 50 eyes Underwent planned ECCE (Extra capsular Cataract extraction) and 50 eyes underwent SICS (Small incision cataract surgery) and the Endothelial cell loss was compared in 2 different technique of cataract surgery. Endothelial cell Loss was estimated using specular microscope (Sp 2000) and all patients were followed up on 1st day, 6th week and 3rd month post-operatively.

Endothelial cell loss was more in superior quadrant in both planned ECCE and SICS (i.e. 12.5% and 12.3% respectively). Central quadrant endothelial cell loss had no Statistical significance in both the groups (Planned ECCE 11.8% and SICS 12.1%). Descements membrane detachment occurred in one case which later developed Bullous Keratopathy. Vitreous loss occurred in two cases. 87% of the eyes which underwent Planned ECCE and SICS showed post operative visual acuity of more than 20/40.

From this study we conclude that endothelial cell loss occurred within Physiological range and it does not lead to corneal decompensation or loss of vision. It was also observed that endothelial cells got stabilized around 3rd month. Lastly there was not much difference in endothelial cell loss in two different types of surgical techniques.
