Abstract Details

Purpose:

The main goal of this project was to evaluate higher-order aberrations of the cornea after phacoemulsification surgery.

Setting:

Department of Ophthalmology Medical University of Warsaw, Poland Head: Professor Jacek P. Szaflik, MD, PhD

Methods:

It was a prospective case series study. The changes were measured with aberrometer KR-1W (Topcon). HOAs of cornea were measured before and after phacoemulsification surgery on 36 eyes of 30 patients. Monofocal foldable IOLs were implanted through a clear-cornea 2.4 mm incision and 1,2 mm side port. HOAs included the total high order aberration (tHOA) in terms of ocular 4mm, corneal 4 mm, internal 4 mm, ocular 6 mm, corneal 6 mm, internal 6 mm, spherical aberration (SA), coma, trefoil, 3rd, 4th, 5th, 6th order aberrations. The incision was measured with AS-OCT CASIA (Tomey).

Results:

The total HOA increased from a mean of (0.209 +/- 0.421) micron preoperatively to (0.249 +/- 0.104) micron postoperatively within 3 mm aperture. Corneal HOA increased from (0.479 +/- 0.079) micron preoperatively to (0.523 +/- 0.123) micron postoperatively with 3 mm aperture. The changes of other HOAs were similar to the total HOA pre- and postoperatively.

Conclusions:

Phacoemulsification cataract surgery does not systematically degrade the optical quality of the cornea. There is a need for further investigations to clarify this tendency.
