Since the early 1980s, civil airmen have been allowed to correct refractive error (i.e., myopia, hyperopia, astigmatism) with corrective surgery. Prior Federal Aviation Administration research studies have shown that the number of civil airmen with refractive surgery continues to increase. A study that reviewed refractive surgery use in civil airmen for the years 1994-96, reported that the larg...

PURPOSE To report a case of laser in situ keratomileusis (LASIK) that used the Intralase femtosecond laser 14 years after radial keratotomy (RK) for residual myopic astigmatism. METHODS A 39 year-old male patient had undergone a bilateral RK operation for myopic correction. The manifest refraction was -1.25 -3.00 x 175 D, with uncorrected visual acuity (UCVA) of 20/50 and best-corrected visua...

Purpose : evaluation of the remote functional and refractive results mixed astigmatism correction in preschool children with “plus” cylinders framework a long-time longitudinal study. Material methods . 38 (75 eyes) aged 1.5–7 years (averagely 4.2 years) 0.75 to 4.25 D 1.85 D) were followed up for 6-15 7.3) years. At first examination, all prescribed permanently wear (+) 0.5 3.5 D. Over follow-...

purpose : to assess the outcomes of laser in situ keratomileusis (lasik) in patients with multiple sclerosis (ms) methods : 15 eyes of 8 patients with ms (2 men and 6 women) who referred for myopia treatment (with or without astigmatism) were undergone lasik. after refractive and visual acuity examinations, topographic and pachymetry screening, intraocular pressure (iop) measurement, biomicrosc...

By Maria Clara Arbelaez, MD Hyperopia-correcting laser surgery can be broadly categorized into intrastromal and surface ablation techniques. Of intrastromal approaches, LASIK is the most popular for the correction of hyperopia. In surface treatments such as PRK, LASEK, and transepithelial PRK, mitomycin C is applied in the majority of cases. Due to differences in epithelial healing, a transepit...

PURPOSE To provide an initial retrospective evaluation of early postoperative outcomes after wavefront-guided myopic LASIK using a new-generation Hartmann-Shack wavefront sensor. METHODS A noncomparative, retrospective study of 243 eyes of 126 patients that underwent primary wavefront-guided LASIK, using wavefront data obtained with a new Hartmann-Shack aberrometer (iDesign Advanced WaveScan ...

INTRODUCTION Laser vision correction for hyperopia is challenging. The purpose of the study was to assess the refractive outcomes of femtosecond-assisted laser in situ keratomileusis (LASIK) for hyperopic correction using wavefront-optimized ablation profiles. METHODS This retrospective case series study included 20 Egyptian patients (40 eyes) with hyperopia or hyperopic astigmatism with a me...

AIMS To report our initial experience with femtosecond lenticule extraction (FLEX) compared with femtosecond laser-assisted in situ keratomileusis (LASIK). SETTINGS AND DESIGN This was a prospective pilot study carried out at the Refractive Surgery Department of the Beyoglu Eye Training and Research Hospital, Istanbul, Turkey. MATERIALS AND METHODS Surgery was performed on both eyes of 14 c...

Just when we thought photorefractive keratectomy (PRK) had achieved a level of safety and predictability in correcting refractive errors in our patients, new wounding healing information regarding apoptosis (programmed cell death) surfaces to show us that the way we remove the corneal epithelium matters a great deal in how the corneal stroma responds to our treatment.1 Excimer laser manufacture...
