Purpose: To optimize artificial intelligence (AI) algorithms to integrate Scheimpflug-based corneal tomography and biomechanics to enhance ectasia detection.

Design: Multicenter cross-sectional case-control retrospective study.

Methods: A total of 3886 unoperated eyes from 3412 patients had Pentacam and Corvis ST (Oculus Optikgeräte GmbH) examinations.

Purpose: To determine the prevalence of laser corneal refractive surgery (laser vision correction [LVC]) among ophthalmologists who perform these procedures and to assess the willingness of these ophthalmologists to recommend LVC to immediate family members.

Setting: Online survey with results analyzed at Surgivision Consultants, Inc., Scottsdale, Arizona, USA.

Purpose: To assess short-term clinical outcomes after implantation of phakic intraocular lenses (Visian ICL, STAAR Surgical Co) in US military warfighters who are not good candidates for laser vision correction.

Methods: A retrospective interventional consecutive case series analysis of all eyes that underwent ICL surgery during a 14-month time period was performed. Main outcome measures included indications for surgery, efficacy, predictability, and early adverse events.

Purpose: To report the refractive results after LASIK for mixed astigmatism at one center with one surgeon comparing two laser platforms.

Methods: A total of 137 eyes of 69 patients were treated with LASIK for mixed astigmatism up to 3.33 diopters (D) using either the ALLEGRETTO WAVE 200- or 400-Hz laser (Alcon Laboratories Inc) between April 2006 and December 2009.

Purpose: To report the use of circular keratotomy in eyes with stage I and II keratoconus to reduce astigmatism.

Methods: A retrospective analysis was performed of all eyes operated from 1993 to 2006 by one surgeon using circular keratotomy for stage I and II keratoconus. Results were evaluated for reduction of corneal astigmatism, refractive stability, and change in best spectacle-corrected visual acuity (BSCVA).

Purpose: To evaluate the long-term refractive stability after LASIK for hyperopia with the WaveLight ALLEGRETTO WAVE Excimer Laser System.

Methods: All 151 patients enrolled in the 2000-2002 FDA study of the ALLEGRETTO WAVE laser were contacted by the investigators approximately 4 years after study completion to be evaluated for refractive stability.

Results: A total of 127/290 (43.

Purpose: To compare visual outcomes using the WaveLight ALLEGRETTO WAVE to administer either wavefront-optimized (standard LASIK) or wavefront-guided (custom LASIK) treatments in myopic eyes.

Methods: In this prospective, open-label, multicenter study conducted in the United States, 374 eyes were randomized by alternating enrollment to receive either wavefront-optimized or wavefront-guided LASIK treatments with this laser platform. Bilateral treatments were administered, with both eyes of each patient receiving the same treatment.

Purpose: To develop a minimum set of analyses and a format for presentation of outcomes of astigmatism correction by laser systems that reshape the cornea.

Methods: An Astigmatism Project group was created under the auspices of the American National Standards Institute (ANSI) Z80.11 Working Group on Laser Systems for Corneal Reshaping.

Purpose: To compare the outcomes of wavefront-guided laser in situ keratomileusis (LASIK) performed using the IntraLase femtosecond laser with the outcomes using the Hansatome mechanical microkeratome.

Setting: Private clinic, Overland Park, Kansas, USA.

Methods: In a prospective contralateral-eye study performed under institutional review board supervision, 51 consecutive patients (102 eyes) had bilateral wavefront-guided LASIK for myopia using the Alcon LADARVision laser.

The authors' study evaluated subjective reports of mesopic visual function after LASIK for spherical and spherocylindrical myopia and evaluated whether age, pupil size, treatment amount, residual postoperative refractive error, or other factors correlated with subjective findings. Preoperative, 3-month, and 6-month subjective patient questionnaires were administered. Results for questions about glare with night driving and glare with bright lights were tallied and evaluated using standard statistical methods.
