Effect of eye laterality on correction of myopic astigmatism with small incision lenticule extraction (SMILE) using vector analysis.

Purpose: To compare the vector analysis, visual, and refractive outcomes after myopic astigmatic correction using SMILE between the right and left eyes.

Methods: This is a retrospective study including 41 right and 40 left eyes that underwent SMILE for correction of myopic astigmatism greater than 0.75 diopters (D) with a follow-up of at least 3 months.

Isolation of acanthamoeba genotype t4 from a non-contact lens wearer from the Philippines.

We report the case of a 76-year old Filipino male who presented with pain, redness, and blurring of vision of the right eye. Corneal scraping was done and sent to the St. Luke's Research and Biotechnology Group for detection and identification of the infectious agent.

Determining corneal power using Orbscan II videokeratography for intraocular lens calculation after excimer laser surgery for myopia.

Purpose: To assess the accuracy of Orbscan II slit-scanning videokeratography for intraocular lens (IOL) calculation in eyes with previous photorefractive surgery for myopia.

Setting: Private practice, St. Louis, Missouri, USA.

Retained contact lens for more than 10 years in a laser in situ keratomileusis patient.

A 49-year-old man with blurred vision in 1 eye and myopic regression had laser in situ keratomileusis (LASIK) in the right eye after having 20/20 uncorrected visual acuity for 2 years. At the conclusion of surgery, a poly(methyl methacrylate) contact lens that had been retained for more than 10 years was discovered in the upper fornix. Although the patient remained asymptomatic, reports of significant complications associated with retained contact lenses are numerous.

Intraocular lens calculations in patients with corneal scarring and irregular astigmatism.

Purpose: To compare various methods of estimating corneal power for intraocular lens (IOL) calculation in patients with irregular corneal astigmatism.

Setting: Pepose Vision Institute, St. Louis, Missouri, USA.

Proper positioning of the plume evacuator in the VISX Star3 excimer laser minimizes central island formation in patients undergoing laser in situ keratomileusis.

Purpose: To identify risk factors in a series of patients who developed steep central islands after laser in situ keratomileusis (LASIK).

Methods: We analyzed and compared the refractive and topographic outcome of a study group composed of 83 eyes of 44 patients who underwent LASIK using the VISX Star3 excimer laser with a refraction-matched control group of 83 eyes treated later. The vacuum aspirator of the excimer laser was abnormally positioned during the surgeries performed in the study group.

Late corneal scarring after photorefractive keratectomy concurrent with development of systemic lupus erythematosus.

Purpose: To report a case of late-onset corneal haze following previous photorefractive keratectomy (PRK) concurrent with the development of systemic lupus erythematosus.

Methods: Single case report and review of medical literature.

Results: A 41-year-old woman underwent uneventful bilateral, non-simultaneous photorefractive keratectomy (PRK) with retreatment of the right eye after 1 year.
