Comparison of refractive and visual acuity results after Contoura® Vision topography-guided LASIK planned with the Phorcides Analytic Engine to results after wavefront-optimized LASIK in eyes with oblique astigmatism.

Purpose: To compare visual acuity and refractive results between topography-guided laser in situ keratomileusis (LASIK) planned with the Phorcides Analytic Engine (PAE) to results after wavefront-optimized (WFO) LASIK in subjects with preoperative oblique astigmatism in their manifest refraction.

Methods: This was a retrospective chart review of clinical results from eyes treated with topography-guided LASIK planned with PAE compared to eyes treated with WFO LASIK using the same Wavelight® excimer laser system. All included subjects had preoperative oblique astigmatism.

Clinical and refractive outcomes after topography-guided refractive surgery planned using Phorcides surgery planning software.

Purpose: To evaluate prospectively the clinical outcomes of topography-guided laser in situ keratomileusis (LASIK) surgery performed with Contoura Vision using the Wavelight excimer laser and planned with the Phorcides Analytical Engine.

Setting: Four clinical practices in the U.S.

The Impact of Image Registration for Ablation Orientation on Clinical Outcomes After Wavefront-Optimized Refractive Surgery in Eyes with Myopia and Astigmatism.

Purpose: To compare the clinical outcomes from laser refractive surgery performed with the same laser with and without incorporating iris registration technology to compensate for ocular cyclotorsion.

Design: Single-site, two-arm, retrospective chart review.

Methods: Clinical outcomes at a single site after wavefront-optimized LASIK using the Wavelight excimer laser with and without the Vario imaging system for iris registration (IR) were evaluated.

Clinical Outcomes After Topography-Guided Refractive Surgery in Eyes with Myopia and Astigmatism - Comparing Results with New Planning Software to Those Obtained Using the Manifest Refraction.

Purpose: To compare clinical outcomes from topography-guided laser refractive surgery based on new planning software to outcomes based on using the manifest refraction.

Design: Single site, two-arm, retrospective chart review.

Methods: Clinical outcomes at a single site after topography-guided LASIK using the Wavelight excimer laser were evaluated, with a target postoperative follow-up time of 90 days.

Case report: the correction of a high magnitude of astigmatism with laser-assisted in situ keratomileusis.

Background: Laser-assisted in situ keratomileusis (LASIK) has undergone several evolutions since it was first approved by the U.S. Food and Drug Administration.

Microsporidial keratoconjunctivitis in a healthy patient with a history of LASIK surgery.

Purpose: To describe a case of microsporidia corneal infection in a HIV-negative patient who did not wear contact lenses.

Method: Case report and review of literature.

Results: This is the first case report of a human immunodeficiency virus-negative individual, a non-contact lens wearer, with microsporidia infection.

Corneal topographic changes and induced astigmatism resulting from superior and temporal scleral pocket incisions.

Background And Objective: To determine the corneal topographic changes that are induced by superior and temporal 5-mm scleral pocket incisions.

Patients And Methods: The authors retrospectively reviewed the records of 43 patients who underwent phacoemulsification with posterior chamber lens implantation through unsutured 5-mm scleral pocket incisions, 24 superiorly and 19 temporally. Corneal curvature was measured using computerized videokeratography, and the induced astigmatism was calculated with the Holladay-Cravy-Koch formula.

Superficial keratitis in treated systemic lupus erythematosus.

A 25-year-old woman with decreased visual acuity and irritation of both eyes was found to have superficial keratitis with keratitis sicca. Her medical record indicated that she had systemic lupus erythematosus. Systemic steroids were necessary to cure the keratitis.
