Association of Patient Satisfaction with Cataract Grading in Five Types of Multifocal IOLs.

introductionThis study investigated patient satisfaction levels in five premium intraocular lenses (IOLs). A secondary aim was to determine whether patient satisfaction was associated with the cataract grade before lens surgery.

methodsIn this multicenter prospective comparative study, 164 patients from diverse backgrounds underwent cataract surgery and were assigned for identical bilateral implantation of multifocal IOLs. In addition to visual performance, quality of life was measured using the National Eye Institute Refractive Error Quality Of Life Instrument (NEI-RQL 42) scoring questionnaire. The Sirius Scheimpflug Analyzer was used to evaluate the posterior cornea and aberrations. Finally, the association of patient satisfaction reports with the Pentacam Cataract Grading Scale (PCGS) and Lens Opacities Classification System (LOCS III) was evaluated.

resultsA considerable subjective improvement was observed in uncorrected far, near (40 cm), and intermediate (60 cm) visual acuity in the five groups (P values < 0.001). A significant difference was observed in mesopic and photopic contrast sensitivity between Symfony, Trinova, and AT LISA at the spatial frequency of 12 cycles per degree, favoring Symfony (P < 0.001). PanOptix users had considerably lower mean coma values (P < 0.001), while AT LISA users had lower mean spherical aberrations (P = 0.009) compared to the other groups. No additional safety concerns relating to IOLs were recorded. Mean satisfaction had a high correlation with LOCS and Pentacam Nuclear Staging (PNS) in each lens group, e.g., correlation coefficient and P value for AT LISA were respectively r = 0.99, P < 0.001 and r = 0.97, P = 0.004.

conclusionDespite discrepancies between groups of lenses, most patients who received multifocal IOLs reported satisfaction at more than 3 years after the initial operation. A growing number of patients with cataracts are seeking spectacle-free vision with presbyopia-correcting IOLs. Hence, the high satisfaction rate among patients with cataract could indicate the value of offering a wider range of available lenses.
