Photorefractive keratectomy (PRK) and laser assisted in situ keratomileusis (LASIK), using an excimer laser, are the currently popular techniques of correcting refractive errors. Since these techniques work by selective ablation of corneal stroma, the tissue healing response plays a great role in the ultimate outcome of surgery. Also, various methods of wound healing modulation can be used to a...

We describe the use and safety of prednisolone acetate eyedrops at the end of laser in situ keratomileusis (LASIK) to aid proper positioning of the corneal flap. The LASIK flap is created using the preferred technique. Following laser ablation and flap repositioning, one drop of prednisolone acetate is instilled on the eye. This delineates the flap "gutters" and allows perfect flap positioning ...

AIMS To investigate the histopathological changes of rabbit corneas after laser in situ keratomileusis (LASIK) and to evaluate the corneal wound healing process. METHODS A LASIK was performed on white rabbit eyes. Postoperatively, rabbits were killed on days 1 and 7, and at 1, 3, and 9 months. RESULTS Periodic acid Schiff (PAS) positive material and disorganised collagen fibre were seen alo...

purpose : to compare changes in posterior corneal elevation, anterior chamber depth (acd), anterior chamber volume (acv) and corneal volume (cv) after laser in situ keratomileusis (lasik ) and photorefractive keratectomy (prk) for low to moderate myopia by pentacam imaging methods : in this prospective comparative case series, 105 consecutive myopic eyes randomly scheduled for lasik (n=59) or p...

DSAEK (Descemet stripping automated endothelial keratoplasty) is one of the options for corneal endothelium disease, which in some patients can result in a residual hyperopia after the procedure. Usually 6 to 12 months after corneal transplantation refraction is already stable. This report describes a therapeutic option used in a 54 years old patient with Fuchs’ endothelial dystrophy submitted ...

Thin-flap laser in situ keratomileusis (LASIK) is a general term used to describe LASIK performed under intentionally created thin flaps of 130 μm thickness or less. Thinflap LASIK has been proven to be a safe, effective, and predictable procedure for myopic refractive corrections (1-6). It has the potential advantage of preserving more posterior corneal tissue available for laser ablation and ...

This 48-year-old white female with chronic optic disc edema is reported for the discussion of the management for the laser vision correction. Two procedures were considered, one was PRK (photorefractive keratectomy) and the other was LASIK (laser-assisted in-situ keratomileusis). A search strategy was developed to search evidence in the literature to support the decision in the selection of the...

In order to model the thermal effect of laser exposure of the iris during laser corneal surgery, we simulated the temperature increase in porcine cadaver iris. The simulation data for the 60 kHz FS60 Laser showed that the temperature increased up to 1.23°C and 2.45°C (at laser pulse energy 1 and 2 [micro sign]J, respectively) by the 24 second procedure time. Calculated temperature profiles show...

P hotorefractive keratectomy for correction of myopia was the first excimer laser-based technique to be developed. During the last 25 years, excimer lasers have improved technologically, several variations of the technique have been developed and preand postoperative pharmaceutical therapies have been investigated. This review article summarises these developments and the published meta-analyse...

OBJECTIVE To describe the use of transepithelial phototherapeutic keratecomy for the long-term treatment of post-laser in situ keratomileusis (LASIK) flap macrostriae. METHOD We present the case of a 22 year old male with visual loss in the left eye due to chronic flap macrostriae that was treated with transepithelial PTK. RESULTS Striae and haze were no longer visible, with a significant i...
