Summary

Multifocal intraocular lenses (IOL) demonstrated good clinical efficiency and safety in Singaporean cataract patients. Visual outcomes were comparable to Western populations, with over half achieving spectacle independence.

Area of Science:

  • Ophthalmology
  • Retinal and Visual System
  • Medical Optics

Background:

  • Cataract surgery is a common procedure to restore vision.
  • Multifocal intraocular lenses (IOLs) offer the potential for spectacle independence after cataract surgery.
  • Evaluating IOLs in diverse populations is crucial for understanding real-world outcomes.

Purpose of the Study:

  • To assess the clinical efficiency and safety of multifocal IOLs in the Singaporean population.
  • To evaluate subjective visual outcomes, including spectacle independence and visual disturbances.
  • To compare outcomes in Singapore with existing literature from Western populations.

Main Methods:

  • Retrospective case series of 45 cataract surgeries with multifocal IOL implantation.

  • Assessment of efficacy, stability, and safety up to six months post-surgery.
  • Telephone interviews to gather subjective visual outcomes and compare with literature.

    • Main Results:

    • Achieved best-corrected distance visual acuity of 0.1 Logmar and N5 near visual acuity at six months.
    • 54.4% of patients achieved total spectacle independence; 22.7% reported glare, primarily at night.
    • Posterior capsular opacification occurred in 38.6% of patients, with 4.55% requiring YAG capsulotomy.

    Conclusions:

    • The Advanced Medical Optics ARRAY multifocal IOL demonstrated good efficacy, predictability, stability, and safety.
    • Subjective visual outcomes in the Singaporean population were comparable to those reported in Western studies.
    • Multifocal IOLs represent a viable option for cataract surgery in Singapore, offering significant spectacle independence.
