Analysis of Topographic Corneal Parameters

Completed

• Conditions: Cornea

• Registration Number: NCT06220578
• Lead Sponsor: Minia University

Brief Summary

The Pentacam HR system (OCULUS) has been suggested to be one of the most sensitive instruments for corneal examination before corneal refractive surgery

Detailed Description

Retrospective non randomized study Analysis of different corneal paremeters obtained by Pentacam for corneal refractive surgery candidates during last 3 years from both sexes between 18 and 45 years K1 - K2 - K max - Pachymetry apex - Pachymetry thinnest - Distance between apex and thinnest - Back elevation - Topography shape - Keratoconus (If present)
