Clinical results after microincision biaxial cataract surgery and implantation of an Incise intraocular lens.

PURPOSE: To evaluate clinical outcomes after uncomplicated microincision biaxial cataract surgery and implantation of Incise intraocular lens (IOL).

METHODS: This study included 47 eyes of 29 patients (mean age 62.2 ± 8.6 years), who underwent 1.4-mm biaxial cataract surgery with implantation of the Incise IOL (Bausch and Lomb). At third month, surgically induced astigmatism (SIA) was calculated. Three, 6 and 12 months postoperatively, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), corrected near visual acuity (CNVA) LogMAR ETDRS, spherical equivalent refraction (SER), photopic distance corrected contrast sensitivity (CS) with and without glare (85 cd/m2 ) (CSV-1000) were assessed. One year after surgery, late complications were assessed and subjects were questioned for subjective symptoms.

RESULTS: Mean of SIA was equal 0.29 ± 0.16 D. Three months postoperatively: mean UDVA improved from 0.83 to 0.04 (p < 0.001), CDVA from 0.58 to -0.05 (p < 0.001) and CNVA from 0.58 to -0.02 (p < 0.001) and all were stable during 1-year follow-up. Three months postoperatively, the mean SER was equal 0.07 ± 0.61 D and was within ±0.5 D in 79%, and within 1 D in 88% of eyes. During follow-up period, corrected CS with and without glare for distance was found to be within normal limits. The only late complication was posterior capsule opacification (PCO). Subjective quality of vision was very high; none of patients complained about glare.

CONCLUSIONS: Biaxial cataract surgery with implantation of the Incise IOL provided excellent clinical outcomes by minimizing SIA, stable refraction and low incidence of PCO.
