Researchers found that eyes treated with LASIK had a better quality of vision than eyes treated with PRK 1 month after surgery, but vision quality normalized for both after the 1-month follow-up, according to a study in the Journal of Cataract & Refractive Surgery.
The study comprised 34 patients (68 eyes) with myopia. Participants had successful myopic LASIK in one eye and PRK in the contralateral eye.
The preoperative questionnaire results showed no significant difference in subjective symptoms and perception of vision of each eye.
At the 1-month postoperative visit, eyes with PRK had significantly worse clarity at night, worse clarity during the day, worse fluctuations in vision and worse double vision or ghosting, according to researchers.
Additionally, patients with high baseline higher-order aberrations reported significantly worse clarity during the day and fluctuation in vision throughout the day.
At the 3-, 6- and 12-month follow-ups there were no significant differences in subjective symptoms between the two eyes. After the 1-month follow-up, there was no significant differences in quality of vision between LASIK and PRK treated eyes.
