Abstract
This study aimed to evaluate the impact of cataract phacoemulsification (PE) on keratometry in patients who had previously undergone non-penetrating deep sclerectomy (NPDS), using anterior segment optical segment coherence tomography (OCT). Methods: We analyzed four clinical cases of PE, two of which were performed with femtosecond laser assistance. Results: During the 12-month follow-up period after PE, no significant effect on keratometric parameters was observed, irrespective of the initial corneal status or the use of a femtosecond laser. OCT data likewise revealed no pronounced structural changes in the NPDS zone following PE.
Keywords: keratometry, induced astigmatism, refraction, cataract phacoemulsification, antiglaucoma surgery.
