The AcrySof ReSTOR IOL and AcrySof Natural ReSTOR IOL provided good visual performance at distance and near under photopic and mesopic conditions. Intermediate vision with both models was reduced compared with distance and near vision.

Patients with bilateral multifocal aspheric IOLs with a lower add had better intermediate and distance near visual acuity than patients with bilateral multifocal spherical IOLs or bilateral aspheric IOLs with a higher add.

Implantation of the collagen copolymer pIOL for moderate to high myopia was safe and effective and provided long-term predictable, stable refractive results.

PURPOSE: To assess the long-term correction of moderate to high myopia using a posterior chamber phakic intraocular lens with a central port design. METHODS: Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refraction, intraocular pressure (IOP), endothelial cell density (ECD), vault, and adverse events over a 5-year period were evaluated retrospectively. RESULTS: A total of 147 eyes (83 patients) were evaluated. Mean postoperative UDVA and CDVA were 0.05 ± 0.11 and 0.02 ± 0.08 logMAR at 1 year and 0.13 ± 0.18 and 0.02 ± 0.09 logMAR at 5 years, respectively. More than 95% of eyes achieved CDVA of 20/25 or better at both follow-up periods. CDVA was unchanged or improved from one to three or more lines in all eyes. Preoperatively, mean spherical equivalent (SE) was −9.20 ± 3.02 diopters (D). At 1 year, the mean SE was −0.17 ± 0.26 D, with 91.53% of eyes within ±0.50 D and 100% of eyes within ±1.00 D of the target. At 5 years, the mean SE was −0.44 ± 0.47 D, with 67.4% of eyes within ±0.50 D and 90.1% of eyes within ±1.00 D of the target. Mean IOP was 12.74 ± 1.65 and 13.0 ± 2.03 mm Hg, at 1 and 5 years, respectively. No significant rise in IOP (> 20 mm Hg) occurred during the follow-up period. Mean ECD was 2,696 ± 358 and 2,645 ± 359 cells/mm 2 at 1 and 5 years, respectively, representing a non-significant loss of 0.43% from preoperative values ( P = .304). Mean vault changed significantly from 398 ± 187 µm at 1 year to 340 ± 163 µm at 5 years ( P < .001). No intraoperative or postoperative complications or adverse events occurred during the follow-up period. CONCLUSIONS: The good long-term outcomes found in this study support the use of this lens with a central port design for the correction of moderate to high myopia.

The Acri.LISA 366D IOL provided a satisfactory full range of vision; a high level of uncorrected and corrected distance, intermediate, and near acuity; and improved contrast sensitivity under photopic and mesopic conditions.

A larger pupil was correlated significantly with better distance visual acuity and with worse near visual acuity. For all pupil diameters, intermediate visual acuity worsened significantly as the distance of the test increased. Distance contrast sensitivity was better with larger pupils at all spatial frequencies in bright-light and dim-light conditions.

The aspheric IOL provided good functional vision at far and near, with lower performance at intermediate distance; good photopic contrast sensitivity and lower mesopic performance; and a low incidence of visual disturbances.
