Premium intraocular lenses: The past, present and future.

ABSTRACT

PURPOSE: To present potential benefits as well as limitations of premium intraocular lens (IOL) use, and provide insight in future of premium cataract surgery. METHODS: Bibliographic research was performed in PubMed/Medline database, and the most recently updated papers were evaluated. Keywords used were premium intraocular lens, multifocal intraocular lens, toric intraocular lens, toric multifocal intraocular lens, accommodative intraocular lens, and the respective brand names. RESULTS: Multifocal IOLs provide uncorrected distance visual acuity (UDVA) of 0.03 logMAR in 82.3%-95.7% of patients and overall spectacle independence in 81%-85% of patients. Toric IOLs provide UDVA of 0.3 logMAR in 70%-95% of patients, residual astigmatism of 1 D or less is noted in 67%-88% of patients, and spectacle independence is reported in 60%-85% of patients. Toric multifocal IOLs provide UDVA of 0.3 logMAR in 92%-97% of patients, and spectacle independence is reported in 79%-90% of patients. Accommodative IOLs represent intensively developing field in ophthalmology, and the results are still variable depending on the IOL model. CONCLUSIONS: Premium IOL technology and advanced surgical techniques have significantly improved postoperative visual outcomes. Future developments will potentiate development of new premium IOL designs that will provide spectacle independence and excellent visual outcomes after cataract surgery.
