IOL Calculations Following Keratorefractive Surgery

, 2005
lation remains a challenge for lens surgery in eyes that have undergone previous keratorefractive surgery. There are two key issues: (1) The estimation of effective lens position (ELP) by the thirdor fourth-generation formulas is not correct when the postoperative corneal power values are used [1, 2]; and (2).

Role of the corneal epithelium measurements in keratorefractive surgery

Current Opinion in Ophthalmology, 2017
Refractive surgery has stimulated considerable progress in corneal and anterior segment imaging, and optical characterization of the eye. From front surface corneal topography, we evolved to three-dimensional corneal tomography with limbus to limbus characterization of the front and back corneal surfaces and pachymetric mapping.

Wound healing in response to keratorefractive surgery

Survey of Ophthalmology, 1993
Over one million Americans have undergone refractive keratoplasty since the introduction of radial keratotomy into the United States in 1978. There are now a number of alternative techniques available for reshaping the corneal surface to alter ocular refractive errors.

Complications of sequential keratorefractive and vitreoretinal surgery

Journal of Cataract and Refractive Surgery, 2006
We describe 2 complications of sequential keratorefractive and vitreoretinal surgery not previously reported. Epithelial ingrowth occurred in 1 patient who experienced laser in situ keratomileusis flap dehiscence and replacement during vitreoretinal surgery.

New Corneal Shapes in Keratorefractive Surgery

Ophthalmology, 1983
The corneal shape change as measured by the Humphrey keratometer and the corneascope after radial keratotomy in 50 patients was compared. The Humphrey keratometer analyzes a unique curve fit algorithm of the aplanatic corneal surface and designates this comparison as a shape factor.
