ABSTRACT
PURPOSE:
To evaluate the visual outcomes and patient satisfaction with angle kappa-customized implantation of SBL-3 (Lenstec, Inc.; +3 D), a rotationally asymmetric multifocal intraocular lens (MIOL).METHODS:
This was a prospective randomized control study. Data from consecutive patients, who underwent bilateral implantation of SBL-3 MIOL from June 2017 to August 2018, were enrolled in the study. One eye of each patient was randomly chosen to receive a horizontal IOL placement (control group), while the other eye received angle kappa-customized placement (design group). The outcomes include uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), defocus curve, contrast sensitivity, quality of vision and patient satisfaction. The follow-up was 3 months.RESULTS:
The study enrolled 80 eyes of 40 patients. There was no significant difference in mean UDVA, UIVA and UNVA between the two groups. The design group showed significantly better visual acuity at -1.50 D of defocus, based on the defocus curve (p = 0.022), and less vertical coma (p = 0.002) than the control group. No significant differences in contrast sensitivity, modulation transfer function, Strehl ratio and patient satisfaction were found between the two groups.CONCLUSION:
Angle kappa-customized implantation of SBL-3 had little impact on visual outcomes and patient satisfaction, except for a moderate impact on intermediate visual acuity.Palavras-chave
