Intermediate vision and correction of presbyopia has become a principal factor in patient’s spectacle independence and satisfaction in modern cataract surgery. First and second generation multifocal intraocular lenses (IOL) have shown consistent decreased visual acuity in intermediate vision. In recent years, various diffractive trifocal IOL have been introduced. We performed a retrospective, observational review to evaluate the performance of a new trifocal diffractive IOL.

A retrospective review of 40 consecutive medical files of all the patients who had cataract surgery and implantation of with trifocal IOL (Panoptix) between March and October 2016 was undertaken. The inclusion criteria included: cataract diagnosis, lens exchange for presbyopia, uneventful surgery, and astigmatism less than 0.75 diopter (D). Exclusion criteria included: previous ocular surgery, past ophthalmic history of ocular disease, complications during surgery and corneal astigmatisms of more than 0.75 D. The main outcomes where uncorrected near (UNVA), intermediate (UIVA) and distance visual acuity (UDVA) after 1 month, spectacle independence, and patient satisfaction. The refractive target was emmetropia. The defocus curves where obtained ( description of the defocus). For statistical analysis, BCVA was expressed in decimals. Quantitatitve parameters were reported as mean and standard deviation. Pre and post operative data was compared by paired samples t-test. A p value <0.05 was considered statistically significant.
Total of 48 eyes (54% females, 46 % males) and mean age at surgery was 65 years old. The mean decimal UNVA, UIVA, and UDVA was 0.68 (SD0.174) (P<0.008.6), 0.71 (SD 0.185) (P<0.061) and 0.788 (SD 0.217)(P<0.003.5) respectively 1 months postoperatively. Spectacle independence was 100% for distance and just 15% patients requiring reading glasses. Patient satisfaction scores for distance were 9.3/10, for intermediate 9.0/10 and for near 8.7/10. None of the patients reported halos or glare, however 85% reported mild starburst in the night. All of the patients said they would recommend the same surgery with the trifocal IOL to other people.
The trifocal IOL used in our research showed significant improvement on the distance, intermediate and near vision after 1 month postoperatively. We found high levels of spectacle independence and excellent patient satisfaction
