Topography-Guided Customized PRK Versus Q-value Adjusted PRK in Correction of Myopia With or Without Astigmatism


Brief description of study

This study will include patients who will undergo PRK in both eyes, for each patient each eye will be randomly allocated to one of 2 procedures:

topography-guided ablation in one eye (group I) and Q-factor customized ablation in the other eye (group II).

Alcon/Wavelight Light Laser Technologie (GmbH, Erlangen, Germany) will be used for photoablation.

The wavelight Topolyzer (Wavelight AG, Erlangen, Germany) will be used before and 1, 3 and 6 months after PRK. Refractive visual outcomes and corneal aberration changes will be compared between the two treatment modalities.

Clinical Study Identifier: NCT03291873
