To determine the incidence and severity of patient complaints typical dry eye recurrent erosion syndrome after excimer laser refractive surgery to compare these symptoms photorefractive keratectomy (PRK) in situ keratomileusis (LASIK).Outpatient university practice.A questionnaire was mailed 1731 patients who had primary myopic PRK or LASIK at least 6 months previously. Questions were designed character ocular dryness their impact on satisfaction willingness have again. Responses from...
Following excimer laser photorefractive keratectomy and other refractive surgical procedures, complaints of halos, glare, monocular diplopia are common. These procedures increase the asphericity cornea, which may cause optical distortions. We used ray tracing techniques to estimate longitudinal monochromatic aberration cornea from measured corneal topography (effective spherical aberration) in 15 normal eyes with varying degrees astigmatism ten after keratectomy. Best corrected visual acuity...
Optical zone diameters in photorefractive keratectomy are small order to minimize the depth of stromal tissue excision and, possible, resultant scarring. A optical demands accurate placement on corneal surface. This article reviews principles that important location and measurement keratectomy. The ablated area should be centered cornea overlying entrance pupil while patient is fixating coaxially with surgeon. An too or decentered may decrease acuity, lessen contrast sensitivity, produce...
Background and objectives Previous studies have demonstrated that transfused blood components from donors with occult hepatitis B virus infection ( OBI ) are potentially infectious. This study reports the results of an Australian lookback programme for period subsequent to commencement individual donation HBV NAT in July 2010 estimates transmission rate two categories donors, confirmed inconclusive (anti‐ HB c reactive non‐discriminated result). Materials methods Using investigations, we...
Purpose To provide 6-month results of a 1-year clinical trial evaluating conductive keratoplasty (CK) for the treatment presbyopic symptoms in emmetropic and hyperopic eyes. Methods A total 143 patients with were enrolled this United States FDA treated to improve near vision 1 eye (unilateral treatment). In addition, 33 fellow eyes distance (bilateral For correction, target refraction was up −2.0 D nondominant eye, 0.0 D. Enrolled had preoperative spherical equivalent plano +2.00 D, no more...
A method is developed for quantifying the strength of moiré effects known as Glass patterns. Unpaired randomly placed dots are added to pattern while discriminability d′ degraded determined in a yes–no test. For given number pairs required increases direct proportion random dots. model based on ideal discrimination an excess oriented pairs. Results conforming Weber's law predicted; dependence amount noise and point also predicted. numerical constant derived from provides measure effect...
To develop a rabbit model of reproducible corneal haze after excimer laser keratectomy and to characterize expression transforming growth factor beta (TGFbeta) basic fibroblast (bFGF) in corneas during formation.Seven rabbits underwent 100 microm deep phototherapeutic (PTK) one eye 15-microm shallow PTK the contralateral eye. Corneal was compared at 1-20 weeks surgery. Subsequently, 16 100-microm Four were killed 1, 2, 3, 4 weeks, respectively, Immunohistochemistry performed on localize...
We report six-month results of the Summit Technology Myopic Keratomileusis Phase I multicenter study. Fifty-seven eyes 57 patients had keratomileusis to correct high myopia. A microkeratome was used for primary keratectomy and excimer laser ablate stroma resected lenticle (cap) or stromal bed (in situ). At six months, 31 47 available follow-up (65.9%) uncorrected visual acuity 20/40 better; 16 (34.0%) 20/25 better. Thirty-seven (78.7%) maintained same (± one Snellen line) best corrected as...
To evaluate the safety of laser in situ keratomileusis (LASIK) patients with autoimmune diseases.Private clinical practice.In this retrospective case series, records who had LASIK at Maloney Vision Institute between June 1, 1998, and October 2004, were reviewed for a history disease including systemic lupus erythematosus, rheumatoid arthritis, psoriatic scleroderma, inflammatory bowel disease, Graves' Reiter's syndrome, Hashimoto's disease. The corneal scleral complications after...
