Abstract Details


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


Private clinical practice, The Eye Institute of Utah


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.


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.


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.
