Submitted: 12/9/08; Accepted: 6/22/10; Posted: 7/15/10In a prospective series of 45 eyes treated consecutively with PRK using a SCHWIND ESIRIS excimer laser, an IOLMaster measurement of the change in corneal curvature did not correlate well with the refractive change, or with the equivalent K readings from the Holladay Report in the Pentacam, requiring a corrective regression formula for the IOLMaster readings.

Submitted: 6/30/09; Accepted: 6/17/10; Posted: 7/15/10In a series of 25 patients, implanted in one eye with an aspheric Akreos AO IOL and in the other eye with a spherical Akreos Fit IOL, the refractive outcome was similar in both eyes, but the quality of vision as measured by the Strehl ratio, higher order RMS aberrations, and amount of spherical aberration with the NIDEK OPD-Scan aberrometer, were better with the aspheric IOL. A useful review of the literature is presented.

Submitted: 11/4/09; Accepted 5/28/10; Posted: 7/1/10Thin-flap LASIK (intended flap thickness of 90- or 120-μm) was performed in a series of 94 eyes, resulting in visual acuity of 20/20 in 98% of eyes with 120-μm flaps and 95% of eyes with 90-μm flaps 6 months postoperatively, with all patients reporting increased quality of life postoperatively. No significant differences were found regarding contrast sensitivity, corrected distance visual acuity, total higher order aberrations, or patient-reported outcomes.

Real Ray Tracing Simulation Versus Clinical Outcomes of Corneal Excimer Laser Surface Ablations
Jens Einighammer, PhD; Theo Oltrup, Dipl-Ing; Thomas Bende, PhD; Benedikt Jean, MD
Submitted: 8/21/09; Accepted: 2/9/10; Posted: 4/1/10In a series of 34 myopic eyes without astigmatism treated by surface ablation with the SCHWIND excimer laser system, the simulation of the Munnerlyn ablation profile showed neither an increase in oblateness of the cornea nor a big increase in higher order aberrations. In contrast, the corneas after real surgery showed increased oblateness and increased corneal higher order aberrations. These findings imply that wound healing and corneal biomechanics may play a role in clinical outcome. A literature review is presented.

Outcomes of Corneal Spherical Aberration-guided Cataract Surgery Measured by the OPD-Scan
Jonathan D. Solomon, MD
Submitted: 6/2/09; Accepted: 11/11/09; Posted: 2/1/10In a series of 40 consecutive eyes with cataract surgery using preoperative corneal spherical aberration as a guide, 3 intraocular lenses (Tecnis Z9003, Alcon AcrySof SN60WF, and Bausch & Lomb LI61AOV) were selected to create a postoperative total ocular spherical aberration near zero. Total postoperative ocular spherical aberration for the entire group measured 0.019 &mirco;m.

Charles E. Campbell, BS
Submitted: 7/14/09; Accepted: 11/3/09; Posted: 12/15/09In a series of 882 eyes measured before vision correction surgery with the VISX laser, smaller pupil methods measured the spherical component better whereas larger pupil measurements measured the astigmatic component better compared to manifest refraction. The spherical equivalent refraction was not optimally measured with any of the four approaches (standard deviation 0.94 D). A manifest refraction should be incorporated in preoperative wavefront-guided excimer laser corneal surgery planning.
