Visual outcomes and patient satisfaction after bilateral implantation of a new trifocal diffractive intraocular lens.

PURPOSE

To assess the visual outcomes, patient satisfaction and spectacle independence following implantation of new diffractive trifocal intraocular lenses.

SETTING

2 centers (university-based practice and a private practice set up).

PATIENTS AND METHODS

Prospective nonrandomized study in which 74 AT LISA TRI 839MP and 8 AT LISA TORIC TRI 939MP IOLs implanted bilaterally in 41 patients following either cataract extraction or refractive lensectomy, follow-up was done at 1st, 2nd and 3rd months to assess the visual and refractive outcomes. Also, a questionnaire was used to assess patient satisfaction, spectacle independence and photic phenomena after the surgery.

RESULTS

Mean uncorrected monocular distance decimal visual acuity (UDVA) was preoperatively 0.35. The averages of uncorrected monocular distance/intermediate/near (UDVA/UIVA/UNVA) postoperatively were 0.90/0.87/0.91 at 3 months. 87.5% patients had SE within ±0.50 by the 3rd month. Nearly all the patients were satisfied with the surgical outcome and the reported photic phenomena by some patients were non-disturbing with noticeable high level of patient's satisfaction by the third month.

CONCLUSION

Diffractive trifocal IOLs can provide with satisfactory visual and refractive results along with positive impact on the performance of vision-related daily activities with minimal level of non-disturbing photic phenomena to patients.
