Photorefractive Keratectomy

International Ophthalmology Clinics, 2000
In this chapter, we have reviewed important aspects of PRK. A thorough understanding of the preoperative assessments, techniques, and postoperative management is essential to achieve satisfactory visual outcomes. Laser safety checks are mandatory. A well-functioning excimer laser with good optics is required.

Photorefractive Keratectomy for Myopia and Photoastigmatic Keratectomy for Astigmatism

Journal of Refractive Surgery, 1997
ABSTRACT BACKGROUND: We conducted a clinical trial to evaluate the efficacy and safety of excimer laser photorefractive keratectomy (PRK) and photoastigmatic refractive keratectomy (PARK) using the Nidek EC-5000 excimer laser. METHODS: A total of 67 eyes from 47 patients whose average age was 35 years were enrolled in the study. The

Photorefractive Keratectomy in Megalophthalmos Anterior

Journal of Refractive Surgery, 2006
ABSTRACTPURPOSE: To evaluate the results of photorefractive keratectomy (PRK) for the correction of myopia and myopic astigmatism in megalophthalmos anterior.METHODS: Four eyes of two brothers with megalophthalmos anterior were treated with PRK. In patient 1, best spectacle-corrected visual acuity (BSCVA) was 20/20 in both eyes with a refraction of -4 ...

Satisfaction after Photorefractive Keratectomy

Journal of Refractive Surgery, 1998
ABSTRACT PURPOSE: To evaluate patient satisfaction one year after photorefractive keratectomy (PRK) for myopia and myopia astigmatism using the Nidek EC-5000 excimer laser. METHODS: This study assessed the level of satisfaction of 6280 patients who underwent PRK after a minimum follow-up of 1 year.

Photorefractive keratectomy in keratoconus suspects

Journal of Cataract and Refractive Surgery, 1999
To compare the refractive outcome after photorefractive keratectomy (PRK) in keratoconus-suspect patients with that in patients with normal corneal topography.Gimbel Eye Centre, Calgary, Alberta, Canada.In a retrospective study, 3 patients (5 eyes) with unusually shaped corneal topography before surgery were selected as keratoconus suspects.

Photorefractive keratectomy in pediatric patients

Journal of Cataract and Refractive Surgery, 1995
This article reports the results of photorefractive keratectomy in nine patients between 10 and 15 years of age who were treated for the following refractive errors: unilateral myopia, post intraocular lens myopia, and unequal hypermetropia with amblyopia. Visual acuity improved and spectacle correction decreased in all patients.

Photorefractive Keratectomy in Ophthalmic Residents

Journal of Refractive Surgery, 2000
ABSTRACT PURPOSE: To find out how ophthalmologists themselves experience the correction of myopia after photorefractive keratectomy. Visuomotor functions were of special interest. METHODS: Four ophthalmology residents and one medical engineer underwent photorefractive keratectomy for myopia.
