PURPOSE To study the influence of the transient elevation of intraocular pressure during suction in laser-assisted in situ keratomileusis (LASIK) on the retinal nerve fiber layer (RNFL) thickness both in microkeratome assisted and femotsecond (FS) LASIK. PATIENTS AND METHODS An interventional case series that included 40 eyes suffering from myopia who were candidates for LASIK. All underwent ...

Background: The most common refractive surgical surgery for the treatment of myopia, hyperopia, and astigmatism is laser assisted in situ keratomileusis (LASIK). A very important step LASIK formation flap. corneal flap was made using a variety microkeratomes. purpose this study to compare central thickness following flap.Methods: This retrospective comparative performed on 200 eyeballs divided ...

PURPOSE To evaluate excimer laser in situ keratomileusis in the treatment of low, high, and excessively myopic eyes in Taiwan, 77 patients (104 eyes) were treated with Nidek EC-5000 excimer laser and divided into four groups. METHODS In situ keratomileusis was performed with a Chiron or SCMD microkeratome. The Nidek EC-5000 excimer laser was used, with multiple passes and a multiple zone abla...

results the mean udva (logmar) improved significantly from 1.13 ± 0.21 preoperatively to 0.24 ± 0.13 postoperatively (p < 0.001), and the mean cdva (logmar) improved significantly from 0.39 ± 0.12 to 0.19 ± 0.09 (p < 0.001). the mean cylinder of manifest refraction decreased significantly by 4.00 diopter (d) (p < 0.001). the mean spherical equivalent error (se) decreased significantly from −6.0...

PURPOSE The localization and distribution of neuropeptide expression in the cat visual pathway can provide information about the function of that pathway. METHOD Study of optic pathway in eight cats. Following extraction of the brain, slices were prepared using a microkeratome. The slices were examined by indirect immunocytochemistry using anti-metenkephalin as antibody to determine the prese...

PURPOSE To describe stromal changes after a femtosecond laser laser-assisted in situ keratomileusis (LASIK) flap was created but not separated. DESIGN Case report. METHODS As part of a randomized paired-eye study comparing LASIK flap creation by a femtosecond laser to a mechanical microkeratome, a femtosecond laser flap was successfully created on one eye of one patient, but the flap was no...
