Abstract Details

Purpose:

To assess the effectiveness of corneal relaxing incisions guided by intraoperative aberrometry following refractive cataract surgery, refractive lens exchange (RLE) or phakic IOL surgery.

Setting:

Private clinical practice, The Eye Institute of Utah

Methods:

This retrospective, non-randomized, non-masked study assessed outcomes after performing corneal relaxing incisions guided by intraoperative aberrometry (Wavetec Vision). 25 eyes of 20 patients who were unhappy with their uncorrected vision following lens-based refractive surgery (RLE, multifocal IOL, phakic implantable collamer lens (ICL, Staar), or femto-laser arcuate incisions) and were found to have residual astigmatism were enhanced with intraoperative aberrrometry-guided corneal arcuate incisions. Postoperative assessments included uncorrected visual acuity and manifest refraction at least one month after enhancement. Student's T-Test was used to compare the pre and post op cylinder and UCVA.

Results:

The mean pre-enhancement uncorrected visual acuity (UCVA) was 20/40-2. The mean post-enhancement was UCVA 20/25-2 (P=0.062) The mean pre-enhancement cylinder was 1.15 D. The mean post-enhancement cylinder was 0.36 D (p=0.0001). Subjects had a mean improvement in UCVA of 2 lines.

Conclusions:

Intraoperative aberrometry-guided arcuate incision enhancement results in effective cylinder reduction and excellent improvement in UCVA in patients with residual astigmatism following lens-based refractive surgery.
