Twelve-month clinical outcomes after implantation of a new, modular, anterior shape-changing fluid optic intraocular lens.

PURPOSE: To report the initial safety and effectiveness profile for an anterior shape-changing, modular IOL, Juvene IOL (JIOL), for the treatment of aphakia and presbyopia after removal of the natural crystalline lens due to cataract.

SETTING

2 private practices in Monterrey and Tijuana, Mexico.

DESIGN

Exploratory prospective multicenter open-label noncomparative clinical trial.

METHODS

A convenience sample of patients aged 50 to 80 years with planned cataract surgery was recruited to undergo unilateral or bilateral implantation with the JIOL. Patients were required to complete an informed consent and be able to dilate to at least 6.0 mm pharmacologically, be in good overall health, and have no significant eye health history to qualify. Visual acuities, defocus curves, and contrast sensitivity were measured for all patients 12 months postoperatively.

RESULTS

51 of 58 eyes completed the 12-month visit. Intraoperative complication rates were extremely low (n = 1; missed base lens tab). The most frequent adverse events (AEs) were prolonged inflammation (N = 6) and cystoid macular edema (N = 4); all AEs were resolved without sequelae by the 12-month visit. The mean monocular logMAR corrected distance visual acuity, distance-corrected intermediate visual acuity, and distance-corrected near visual acuity were 0.01, 0.08, and 0.24, respectively. Defocus testing showed visual acuity > 20/40 from approximately +1.00 through -2.00 diopters. Binocular implantation (n = 16) provided superior performance over monocular implantation.

CONCLUSIONS

The JIOL offers a new solution to treat presbyopia, providing clear functional vision performance across a range of distances with an acceptable initial safety profile.
