Simultaneous and Sequential Photorefractive Keratectomy

Journal of Refractive Surgery, 1995
ABSTRACT The purpose of this study was to show the safety, effectiveness, and predictability of simultaneous bilateral as compared to sequential unilateral photorefractive keratectomy in 273 normally sighted myopic eyes. An excimer laser with a fluence of 180 mj/cm p 2 at a frequency of 10 Hz was used at ...

Thermal Consequences of Photorefractive Keratectomy

Cornea, 2001
Photorefractive keratectomy (PRK) is still a widely used method for the correction of refractive error despite the advent of laser in situ keratomileusis (LASIK). However, both procedures are associated with significant side effects such as corneal haze and regression.

Photorefraction

Archives of Ophthalmology, 1987
Although precise prevalence figures regarding amblyopia and strabismus are not easily obtained, most studies suggest that at least 5% of the population is affected by these disorders. 1,2 In a large percentage of patients, they go undetected and untreated. A survey of 6768 youths 12 to 17 years old showed that more than 5% had strabismus, yet only 1.4%

The Photorefractive Nonlinearity

2003
Chapter 2 on light propagation in nonlinear optical media describes the origin of self-focusing of beams in nonlinear optical media in general. It shows how these focusing effects can be exploited to create optical spatial solitons. Starting with one-dimensional transverse soliton phenomena the general features of soliton formation which lead to a ...
