Prospective clinical study.
A PC pIOL was implanted in highly myopic eyes of consecutive patients. Standardized follow-up examinations including uncorrected (UDVA) and corrected (CDVA) distance visual acuities and refractions were performed 1, 3, and 6 months and 1, 2, and 3 years postoperatively.
The patient cohort consisted of 30 eyes of 16 patients. The study eyes had a mean manifest refraction spherical equivalent of −10.1 diopters (D) ± 3.4 (SD), which decreased to −0.3 ± 0.8 D postoperatively. After 3 years, all eyes achieved (47%) or exceeded (53%) their preoperative CDVA, thus improving the mean CDVA from 20/21 (0.94) preoperatively to 20/18 (1.14) postoperatively. The mean postoperative UDVA (20/20 [0.98]) resembled the preoperative CDVA (20/21 [0.94]). When analyzing all eyes with good visual potential (preoperative CDVA 20/20 or better; n = 18), 94% achieved a postoperative UDVA of 20/20 or better. One small-diameter PC pIOL contacted the crystalline lens, which led to slight anterior subcapsular lens opacification. Despite this, the patient achieved a CDVA of 20/20.
The 3-year results of this pilot study of a new PC pIOL showed good efficacy and safety.
