Abstrakt: Purpose: To assess the visual outcomes in patients bilaterally implanted with novel Clareon® intraocular lens when targeting mini monovision post-operatively. Setting: The study was conducted at Laxmi Eye Institute; it is a tertiary care eye institution in Panvel, India. Design: This is an investigator initiated, prospective, single-centre longitudinal study of 45 patients to assess the visual outcomes in patients who were implanted with Clareon ® IOL bilaterally. Methods: Patients with corneal astigmatism of ≤ 0.75 D who underwent bilateral cataract surgery with pseudophakic mini-monovision and implanted with novel Clareon® intraocular lens were included. Patients having post op manifest refraction >± 0.25 D in the dominant eye and <− 0.5 D or >− 0.75 D in the non-dominant eye were excluded. The main study outcomes were assessed at 1 and 3 months; it included uncorrected visual acuities assessment, defocus curve, and patient reported spectacle use. Results: The mean (SD) binocular distance corrected intermediate visual acuity at 3 months was 0.22 (0.09) LogMAR. At 3 months, 54% of patients enjoyed 0.4 LogMAR or better BUCNVA. The defocus curve showed good distance and intermediate visual acuity with > 0.2 LogMAR vision from +0.50 D to − 1.50 D. We found a positive correlation between the Q value of the dominant eye and the BCIVA at 3 months postoperatively, however it was not statistically significant. The Q value was more negative when the intermediate vision was closer to 0 LogMAR. Post operatively, at  3 months,  95% patients did not need glasses for distance and intermediate vision and 73% of patients were comfortable for intermediate vision without glasses all the time. Conclusion: Mini-monovision with Clareon® monofocal IOL implantation can offer overall satisfactory vision for far and intermediate distances with minimal need for use of spectacles for near vision.
