We report on a 72 year-old pseudophakic patient who had been implanted with a monofocal intraocular lens, and who underwent a unilateral Supracor laser-assisted in-situ keratomileusis (LASIK) procedure to correct presbyopia and hyperopia. Uncorrected near visual acuity was improved, but the patient complained of glare, halo, reduced distance vision, and… (More)
BACKGROUND To evaluate the safety and effectiveness of the Supracor excimer laser algorithm to treat hyperopic presbyopic patients using laser in-situ keratomileusis (LASIK). METHODS This is a retrospective case review of patients diagnosed with hyperopia (Sphere ≥ +0.0 D and presbyopia reading add ≥ 1.0 D) who underwent Supracor excimer laser treatment… (More)
A cylindrical optical backplane using Plexiglas stacked disks, light-emitting diodes, and p-i-n photodiodes is described. The main advantage of the design is its simplicity and lack of both precision optics and critical alignment requirements.
