Keratophakia and Keratomileusis

Ophthalmology, 1984
We present ultrastructural findings in two cases, one of keratophakia (9 months postoperatively) and one of keratomileusis (1 year, 7 months post-operatively), which best demonstrate the pathologic changes we observed in six cases of cryorefractive surgery. In addition, we studied a rabbit model of keratophakia which appears to exhibit similar features

Optical Zone Size in Keratomileusis for Myopia: Computer-Assisted Evaluation and Correction of Myopic Keratomileusis

Journal of Refractive Surgery, 1991
ABSTRACT: In this article, we demonstrated the unexpected reduction of optical zone diameter in myopic keratomileusis and its causes. Mathematical evaluation of optical zone diameter was made possible through a module added to a computer program. Optical zone diameter was reduced more in smaller corrections than in higher corrections.

Results of pediatric laser in situ keratomileusis

Journal of Cataract and Refractive Surgery, 2000
To evaluate the results of laser in situ keratomileusis (LASIK) for uniocular high myopia in pediatric eyes.Dr. Agarwal's Eye Hospital, Chennai (Madras), India.Sixteen eyes that were treated by LASIK for uniocular high myopia were retrospectively analyzed. The mean patient age was 8.4 years +/- 1.83 (SD) (range 5 to 11 years).

Laser in situ Keratomileusis for Myopia

Journal of Refractive Surgery, 1998
ABSTRACT PURPOSE: To evaluate the efficacy of laser in situ keratomileusis (LASIK) for myopia. METHODS: We performed LASIK on 55 eyes using the Nidek EC-5000 excimer laser. We altered the PRK algorithms to make them appropriate for LASIK. The Chiron automated corneal shaper was used to create the flap. RESULTS: A high rate

Butterfly Laser Epithelial Keratomileusis for Myopia

Journal of Refractive Surgery, 2002
ABSTRACT PURPOSE: Decreased epithelial viability is a postoperative complication of standard laser epithelial keratomileusis (LASEK) that hampers rapid recovery, and causes reduced visual acuity as well as discomfort. We present a new LASEK technique that, by increasing epithelial viability, reduces the occurrence of these complications.

Myopic Keratomileusis by Excimer Laser on a Lathe

Journal of Refractive Surgery, 1994
ABSTRACT BACKGROUND: We designed an excimer laser keratomileusis delivery system to increase the regularity of the refractive cut surface and allow greater precision in the level and shape of the ablated zone. METHODS: A parallel faced corneal disc was produced by microkeratectomy from six human eyes and surgical keratectomy in 12 ...

Laser in situ Keratomileusis vs. Laser Epithelial Keratomileusis (LASIK vs. LASEK)

Journal of Refractive Surgery, 2001
ABSTRACT PURPOSE: To compare results of laser in situ keratomileusis (LASIK) and laser epithelial keratomileusis (LASEK) for the treatment of myopia. METHODS: Two groups of fifteen patients (30 eyes) each were assigned to either the LASLK group or the LASEK group.

Homoplastic Keratomileusis for the Correction of Myopia

Journal of Refractive Surgery, 1985
ABSTRACT: The authors performed primary homoplastic myopic keratomileusis (MKM) on ten eyes with a minimal followup of three months. The mean preoperative refractive error was -15.13 diopters, Postoperatively, the mean myopia was -0.89 diopter. The surgical accuracy was 93% ± 8.6% with a correlation coefficient of 0.98.

Laser Epithelial Keratomileusis for Myopia

Journal of Refractive Surgery, 2003
ABSTRACT PURPOSE: To describe a new technique for excimer laser corneal surgery: laser epithelial keratomileusis (LASEK). METHODS: We report 76 eyes with spherical equivalent refractive myopia ranging from -8.00 to -22.00 D (mean -11.00 ± 3.00 D).
