Outcomes of refractive error correction in pseudophakic patients using a sulcus piggyback intraocular lens.

PURPOSE: The purpose of this study was to assess the results of a sulcus intraocular lens (Sulcoflex) for pseudophakic refractive errors following phacoemulsification cataract surgery. METHODS: This retrospective clinical observational cohort study included consecutive eyes in which a Sulcoflex was implanted. Uncorrected distance visual acuity and corrected distance visual acuity as well as refractive outcomes were assessed. The minimum follow-up time required for inclusion was 3 months. RESULTS: In total, 15 eyes (n = 15) were evaluated. The mean follow-up was 14 months (range: 3-18 months). The Sulcoflex aspheric (653L) was implanted in 13 eyes and the Sulcoflex toric (653T) in two eyes. The preoperative mean logMAR (Snellen) uncorrected distance visual acuity and corrected distance visual acuity were 0.88 (20/150) and 0.27 (20/40), respectively. The postoperative mean logMAR (Snellen) corrected distance visual acuity was 0.15 (20/30). The preoperative mean spherical equivalent was -0.22 ± 5.95 D and the postoperative mean spherical equivalent was -1.59 ± 1.45 D. There was a significant and strong correlation (r = 0.64, p < 0.001) between the attempted and the achieved spherical equivalent. CONCLUSION: The Sulcoflex is a safe and viable option for patients with residual refractive error following cataract surgery.

Patient satisfaction and visual function after pseudophakic monovision.

PURPOSE: To evaluate the visual outcomes and patient satisfaction with modified pseudophakic monovision. SETTING: Tertiary teaching hospital. METHODS: This prospective study comprised patients with emmetropia after first-eye cataract surgery who were offered monovision for the second-eye surgery with a moderate myopic target refraction (-1.00 to -1.50 diopters [D]). Visual acuity, contrast sensitivity, stereopsis, patient satisfaction, and degree of spectacle independence were measured preoperatively and 3 to 4 months postoperatively. RESULTS: The study evaluated 52 eyes of 26 patients with a mean anisometropia between the near eye and the distance eye of 1.16 D. Uncorrected distance visual acuity was at least 20/30 in 96% of patients, with 92% achieving N8 (J4) or better uncorrected near acuity. Good stereopsis and contrast sensitivity were maintained. Patients were generally satisfied with the surgery. One fourth of patients were completely independent of spectacles; 1 patient was totally dependent on spectacles. No patient required intraocular lens (IOL) exchange or other refractive corrective procedures. CONCLUSION: Monovision with modest refractive targets achieved good visual function and patient satisfaction without the inherent risk for troublesome visual symptoms associated with multifocal IOLs.
