PURPOSE: To present biometric predictability, evaluating postoperative refraction and visual acuity in eyes submitted to multifocal intraocular lens implantation. METHODS: Retrospective study in 88 eyes of 50 patients, submitted to phacoemulsification with multifocal lens implant of three commercial brands: ReSTOR, ReZoom and Tecnis. For biometric examination were used: optic biometry associated to the use of tomography of anterior segment and Holladay II biometric formula. With postoperative refraction, visual acuity and implanted IOL, according to Holladay II formula, we calculated the value of IOL to be implanted in case we used SRKT and Haigis formulas. The results were evaluated according to statistical methods. RESULTS: All eyes obtained a visual acuity equal or higher to 20/40 and J3 without correction. Holladay II, SRKT and Haigis formulas presented similar performance in all groups. CONCLUSION: Biometric predictability is improving with the use of optical biometry and last generation formulas.
