Femtosecond Laser-assisted Lens Surgery with Low-energy Pulse versus Conventional Phacoemulsification for Presbyopia Correction: An Intraindividual Study

Background: Lens surgery with multifocal IOL implantation for presbyopia correction is performed by femtosecond laser-assisted lens or conventional phacoemulsification. Objective: To compare the clinical results of low-energy pulse phacoemulsification intraindividually. Methods: Charts from patients who underwent Refractive Exchange (RLE) in a single center, Femtosecond Laser-Assisted Surgery (FLALS) one eye and Conventional Phacoemulsification (CP) other, were retrospectively reviewed. All eyes had same Intraocular (IOL) implanted. The outcomes level satisfaction questionnaire compared between two groups according to technique employed (FLALS vs. CP) period up four years. Stability, efficacy safety indices also assessed. Results: This study comprised total 56 28 randomly assigned FLALS CP other. No statistically significant difference was observed techniques regarding postoperative visual acuities, duration surgical procedure, indexes (p>0.05). Refraction stable all eyes, whereas change occurred 2 (7.1%) operated upon 6 months postoperatively, but without statistical significance (p˃0.05). Satisfaction slightly better not (p=0.134). immediate myosis other adverse events after laser registered. Conclusion: parameters assessed showed no differences techniques, spite refraction stability postoperatively.
