Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate the rotational stability of toric intraocular lenses (IOLs) in pseudophakic eyes over a 6- month follow-up period and assess their impact on visual functionTimepoint: 1 month ,3 month ,6 month | — |
Secondary
| Measure | Time frame |
|---|---|
| To evaluate the positional stability of Toric intraocular lenses over a 6 month follow - up period and assess their impact on visual function. This will be achieved by analyzing the following parameter 17 • IOL decentration (iTrace) • IOL tilt (AS-OCT) • Anterior chamber depth (IOL Master & AS-OCT) • Visual acuity (UCVA & BCVA) • Higher-order aberrations (iTrace) • Strehl ratio (iTrace) 2)To compare the two toric IOL designs included in the study—differing in haptic design and material—based on the above measurements. The objective is to determine whether one lens design demonstrates superior in vivo stability or results in better visual & optical outcomes across the postoperative period.Timepoint: 1 week, 1 month, 3 month , 6 month | — |
