Enhanced Partial Range of Field Intraocular Lenses Improve Intermediate Visual Acuity

Strategic Insights -

Researchers from Germany have reported new findings on the effectiveness of partial range of field (PROF) intraocular lenses (IOLs) in enhancing intermediate visual acuity. The study, which was supported by Johnson and Johnson Vision Care, investigated visual and patient-reported outcomes in patients implanted with the PROF IOL ICB00. The ambispective, single-center study included 41 patients, who were evaluated for visual acuities, refraction, and patient-reported outcomes 18 months post-surgery.

Key Takeaways:

  • The study found that 100.0% of patients achieved binocular visual acuity of 0.20 logMAR or better for uncorrected or corrected distance vision, highlighting the effectiveness of PROF IOLs in improving distance visual acuity.
  • However, the results also showed that only 73.2% of patients achieved binocular visual acuity of 0.20 logMAR or better for uncorrected intermediate vision, indicating a potential limitation of PROF IOLs in enhancing intermediate visual acuity.
  • Photic phenomena were reported by 16% of patients, suggesting a possible side effect of PROF IOL implantation.
  • The study's methodology was reviewed and approved by the medical ethics committee of the Medical Chamber of North-Rhine, Germany (CE # 2124770CE01).
  • The research team consisted of Annika Licht, Catharina Latz, Katharina A. Ponto, Johannes Menzel-Severing, David P. Pinero, and Alireza Mirshahi.
  • The study's findings have implications for the development of IOLs that can improve both distance and intermediate visual acuity.

Statistics:

  • 100.0% of patients achieved binocular visual acuity of 0.20 logMAR or better for uncorrected or corrected distance vision.
  • 73.2% of patients achieved binocular visual acuity of 0.20 logMAR or better for uncorrected intermediate vision.
  • 79.5% of patients achieved binocular visual acuity of 0.20 logMAR or better for distance-corrected intermediate vision.
  • 16% of patients reported photic phenomena.
  • The study included 41 patients, aged 48-84, who were implanted with the PROF IOL ICB00.
