Trial Outcomes & Findings for Evaluation of Glistening, Visual Outcomes and General Safety 24 Months Post-IOL Implantation (NCT NCT07297719)

Evaluation of Glistening, Visual Outcomes and General Safety 24 Months Post-IOL Implantation

Glistening count: Number of glistenings (=microvacuoles) in the illuminated field were counted by slit lamp examination at the study visit 24 months post IOL implantation of the study eye. Lower glistening counts indicate a better outcome (=fewer glistenings).

Glistening density evaluation: Number of glistenings in the illuminated field were counted by slit lamp examination at the study visit 24 months post IOL implantation of the study eye. The number of glistenings were recorded and the density of microvacuoles per square millimeter (MV/mm²) was calculated. Lower glistening density values indicate better outcome (=fewer glistenings).

Glistening grading (Miyata classification): At the 24-month post-IOL implantation visit, the number of glistenings/microvacuoles (MV) in the illuminated field of the study eye was counted by slit-lamp examination. Glistening density was expressed as microvacuoles per square millimeter (MV/mm²) and graded using the Miyata Glistening Density Grading Scale (grades 0-3), where the minimum glistening level corresponds to grade 0 (\<25 MV/mm²) and the maximum to grade 3 (101-200 MV/mm²).0 corresponds to \<25 MV/mm² and grade 3 to 101-200 MV/mm². Lower Miyata grades indicate a better outcome (=fewer glistenings).

Monocular Corrected Distance Visual Acuity (CDVA) was assessed for each study eye using a standardized visual acuity chart under photopic conditions with the subject's best refractive correction in place. CDVA was recorded in logarithm of the Minimum Angle of Resolution (logMAR), with typical values ranging from about -0.3 (approximately 20/10 Snellen acuity) to 1.0 (approximately 20/200 Snellen acuity), where lower logMAR scores indicate better vision.

Subjective (manifest) refraction was performed under photopic conditions using standardized logarithmic visual acuity charts. For each study eye, manifest refraction was conducted to determine the best refractive correction. Sphere, cylinder, and axis were recorded, and spherical equivalent (SE) was calculated. SE values are reported in diopters (D). SE values closer to 0.00 D indicate a better refractive outcome (i.e., less residual myopia or hyperopia or astigmatism). An SE value within approximately ±0.50 D is generally considered a good refractive result.
