PARTIAL TOPOGRAPHY-GUIDED PHOTOREFRACTIVE KERATECTOMY FOLLOWED BY CORNEAL CROSS LINKING IN THE MANAGEMENT OF PROGRESSIVE KERATOCONUS: OUR INITIAL TEN-MONTH RESULTS.

The aim was to assess the results achieved in keratoconic corneas submitted to the combined partial topography-guided photorefractive keratectomy (TG-PRK) and corneal cross linking (CXL) procedure performed on the same day. Four patients underwent this treatment of one eye. Corneal epithelium removal was performed by 50-micron phototherapeutic keratectomy.

Late Stage of Corneal Decompensation Caused by Progressive Keratoconus: Can We Treat It and Save the Cornea?

Aim. To report a case of 40-year-old male with progressive bilateral keratoconus who had undergone transepithelial phototherapeutic keratectomy (TE-PTK) and corneal collagen cross-linking (CXL) using hypoosmolar riboflavin solution in a same day procedure. Methods.

Astigmatism and diagnostic procedures.

Astigmatism represents an inability of the cornea and lens to provide a sharp image onto the retina. Correcting astigmatic errors, whether congenital, contact lens induced or surgically induced, is now an integral part of modern cataract and refractive procedures. Development of modern technology has enabled accurate diagnosis and perfect opportunities for correction; however, while cataract and keratorefractive surgery have come a long way in the last decade, the treatment and diagnosis of astigmatism continue to challenge ophthalmologists.

Sub-Bowman keratomileusis compared with photorefractive keratectomy--contralateral eye study.

The aim of this study was to compare two different refractive surgery approaches in correction of myopia with or without astigmatism. In patients where one eye underwent sub-Bowman keratomileusis (SBK) and the other eye photorefractive keratectomy (PRK), the objective and subjective results were retrospectively compared during the six-month follow-up. Eighty four patients (168 eyes) were involved in this retrospective contralateral study.
