Abstract Details

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.

Setting:

Asian Eye Institute, Makati City, Philippines

Methods:

This is a prospective study of patients who underwent femtosecond laser-assisted cataract surgery and implantation of a polyfocal bioanalogic IOL. Patients 40 years and above with bilateral cataracts were recruited. 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:

10 patients (20 eyes) have reached six month follow up. Mean age was 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. Patients 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).

Conclusions:

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. Femtosecond laser provide large, round capsulotomy, better centration and stable positioning. Consistency in surgical technique can help give consistent surgical outcomes. Polyfocal, bioanalogic intraocular lens provide seamless range of vision from distance to intermediate to near, less glare, haloes, and excellent contrast sensitivity. It seems to be rational choice because it addresses the drawbacks of multifocality.
