Visual Outcomes After Femtosecond Laser–Assisted Cataract Surgery and Bilateral Implantation of Polyfocal Bioanalogic IOL
Purpose
To evaluate the refractive outcomes and the distance, intermediate and near visual acuity achieved by patients after bilateral implantation of a bioanalogic, polyfocal intraocular lens.
Methods
This is a prospective study of patients who underwent femtosecond laser-assisted cataract surgery and bilateral implantation of a polyfocal bioanalogic IOL in both eyes. The polyfocal bioanalogic IOL is a new concept which resembles the natural crystalline lens by the material and optical design. Follow-up examinations included uncorrected and corrected visual acuity (VA) for far, near (40cm) and intermediate (70cm) distances, subjective refraction and contrast sensitivity under different lighting conditions. The quality of vision, glare, halos, spectacle independence and the personal satisfaction of the patients was assessed with a questionnaire.
Results
Ten patients (20 eyes) have reached six month follow up. Mean age 62.3 years, (48-72 years). At six month, the mean sphere was +0.44D, mean cylinder was -0.73D and mean spherical equivalent was +0.05D. Mean monocular UDVA is 0.02logMAR, UIVA 0.08logMAR and UNVA 0.25logMAR. Mean binocular results UDVA -0.02logMAR, UIVA 0.04logMAR and UNVA 0.2logMAR. Patient's contrast sensitivity photopic and mesopic results are excellent (on or above population norm). 100% patients did not need glasses for daily activities, driving and reading. Only 10% of patients reported Grade 4 Halo (measured on glaremeter).
Conclusion
Study results at six month showed that refractive outcomes achieved were near emmetropia and monocular and binocular uncorrected distance, intermediate and near vision were very good. The femtosecond laser consistently provided large, round capsulotomy, better centration and stable positioning.
