Abstract Details

Purpose:

Cataract is the leading cause of blindness in the world. It was estimated that 20% of cataract surgery were done in diabetic patients. There are increased vulnerability of corneal endothelial cells to damage induced by intraocular surgery in diabetic patients. Torsional ultrasound features oscillating rotary side movement, therefore improving the energy efficiency. The purpose of this study is to compare the postoperative corneal endothelial cell density loss between torsional and longitudinal phacoemulsification mode in immature senile cataract with type 2 diabetes mellitus.

Setting:

This study was conducted in Cataract and Refractive Surgery Unit, National Eye Center Cicendo Eye Hospital, Bandung, Indonesia

Methods:

This is a double blind randomized controlled trial study, done from November 2014 until January 2015. The subjects of this study were immature senile cataract patients with type 2 diabetes mellitus, aged 55- 65 years old who came to cataract and refractive surgery clinic. Subjects were randomly assigned to torsional and longitudinal phacoemulsification done by one experienced phaco surgeon. Ultrasound time (UST), and cumulative dissipated energy (CDE), were evaluated. Specular biomicroscopy were done preoperatively and on postoperative day seven. Statistical analysis used were independent T Test and Pearson correlation test.

Results:

The torsional group showed less endothelial cell density loss (400,15±309,82 versus 880,16±406,25) at postoperative day seven. Pearson Correlation test revealed positive correlation between CDE and UST with endothelial cell loss (correlation coefficient of 0.59 and 0,58).

Conclusions:

Torsional phacoemulsification gives less endothelial cell density loss as compared to longitudinal phacoemulsification in immature cataract with type 2 diabetes mellitus patients.
