Follow-up examinations were conducted at day 1, 1 week, 1 month, 6 months, and 12 months. Postoperatively, 1 month onward evaluation of uncorrected and distance-corrected far and near visual acuity; reading acuity and reading speeds (using Salzburg Reading Desk) at 70, 80, and 90 cm; contrast sensitivity; defocus curves; and patient satisfaction was carried out.Results: Fifty eyes from 25 patients with a mean age of 58±13.44 years were included. All eyes showed significant improvement in spherical equivalent, uncorrected distance visual acuity, corrected distance visual acuity, uncorrected near visual acuity, and corrected near visual acuity at 1 month compared to preoperative values (P<0.05), with no significant change in these parameters thereafter until the last follow-up (P>0.05). At 12 months, mean uncorrected reading acuities and reading speeds at 70, 80, and 90 cm were in the range of 0.09–0.04 logMAR units and 153.6–169.0 words per minute, respectively, with significantly better results at 80 cm. Five eyes underwent YAG laser capsulotomy for early posterior capsule opacification (PCO) at a mean follow-up of 7.2±2.9 months. Contrast sensitivity scores at 12 months were comparable to 1 month (P>0.05 for all spatial frequencies). All patients reported good tolerance and 100% independence from spectacles for all activities.Conclusion: Trifocal IOLs provided excellent unaided vision at all distances. Reading performance was good through the complete intermediate distance range. PCO occurrence and subsequent YAG capsulotomy did not affect the long-term visual outcomes.Keywords: diffractive, trifocal, salzberg reading desk, reading speeds, intermediate vision, patient satisfactionGanesh SBrar SPawar ADove Medical PressarticleTrifocalIntraocular lensFunctional visionSalzburg Reading DeskOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 11, Pp 1453-1459 (2017)
