Crystal Clear Choices: Unveiling The Visual Brilliance – Osi Comparison In Multifocal Vs. Trifocal Intraocular Lenses After Cataract Extraction Surgery With High-Definition Analyzer

To analyze and compare whether the multifocal or trifocal intraocular lens has the better optical quality of the eye depending on OSI.

To assess visual outcomes between the multifocal intraocular lens and trifocal intraocular lens.

Study design: Single-center  ,Prospective, interventional, nonrandomized conducted at Nethradhama Super-Specialty Eye Hospital, Jaynagar, Bangalore for a Duration of  2 years (August 2022 – August 2024)

The study compared the postoperative performance of 100 multifocal and 100 trifocal intraocular lenses in patients undergoing cataract surgery, focusing on the Objective Scattering Index (OSI) measured on days 1 and 15 using an HD Analyzer. Patients were divided into two groups based on the type of lens they received. This approach aimed to assess and compare the early postoperative optical quality of multifocal versus trifocal lenses

The study found that on postoperative day 1, the mean Objective Scattering Index (OSI) measured using the HD Analyzer (HDA) was 4.17 ± 3.61 for patients with multifocal lenses and 4.30 ± 2.89 for those with trifocal lenses P<0.05. By postoperative day 15, the mean OSI decreased to 1.88 ± 0.89 for the multifocal lens group and to 2.78 ± 1.49 for the trifocal lens group. P<0.05. These results indicate a significant improvement in optical quality from day 1 to day 15 post-surgery in both groups, with the multifocal lens group showing a greater reduction in OSI.

The study observed a substantial enhancement in optical quality from postoperative day 1 to day 15 for both multifocal and trifocal lens groups, as indicated by a decrease in the Objective Scattering Index (OSI). The multifocal lens group exhibited a more pronounced reduction in OSI, emphasizing notable improvements in visual outcomes following surgery within both lens categories.
