Abstract Details

Purpose:

evaluate the effect of single and pared opposite 3.0 mm clear corneal incisions on corneal astigmatism during phacoemulsification cataract surgery at steep meridian

Setting:

Laser Eye Clinic

Methods:

Thirty eyes of 30 patients underwent phakoemulsification cataract surgery.The subjects randomized into paired or single incision groups in a prospective study.In paired incision group we made first 3.0 mm clear corneal incision at steepest meridian,and a second 3.0 mm incision exactly 180 degrees apart,plus a 1.3 mm port incision for second instrument at 80- 90 degrees distance.In the single incision group only one 3.0 mm incision at steepest meridian and a 1.3mm port incision created.Standard phacoemulsification surgery proceeded with capsulorhexis,hydro-dissection, nucleus phacoemulsification and IOL placement.All patients were inserted SA60AT hydrophobic IOL.After 3 month we evaluate their refraction,keratometry and corneal topography.

Results:

Post-operative refractive corneal plane astigmatism was 1.75 +/- 0.84 diopter in the single incision group, and 1.32 +/- 0.82 diopter in the paired opposite incision group . Mean keratometric surgically induced astigmatism was 1.01 +/- 1.05 diopter in single incision group and 1.56 +/- 0.70 in paired opposite incision group . Topographic mean 3mm central corneal irregularity was 1.68 +/-0.46 and 1.64 +/- 0.65 in single and paired incision groups respectively

Conclusions:

Clear corneal incisions at steepest meridian during phacoemulsification cataract surgery are effective for reduction of pre-existing corneal astigmatism . The effectiveness of paired opposite 3.0 mm clear corneal incisions at steepest meridian during phacoemulsification cataract surgery are more effective than single incision.
