Brief Summary

"Comparison between Lathe Cut versus Cast Molding Soft Contact Lens Technique on Ocular Surface Integrity" investigates the impact of two different manufacturing methods on the health and integrity of the ocular surface.

Detailed Description

The study aims to determine which technique, lathe cutting or cast molding, produces soft contact lenses that are more biocompatible and less likely to cause adverse effects on the eye. The findings from our research could have significant implications for contact lens wearers and manufacturers, guiding the production of lenses that promote better ocular health and enhance wearer comfort. Ultimately, this research contributes valuable knowledge to optometry and ocular surface disease management.
