Assessment Of Intermediate And Near Visual Acuity After Ct Lucia Monofocal Aspheric Iol Implantation

To evaluate visual acuity at different distances and quality of vision after cataract surgery with CT LUCIA aspheric IOL implantation

All patients were operated from September to October 2024

In this prospective observational study 24 patients (48 eyes) underwent bilateral phacoemulsification and were implanted with CT LUCIA 621P (ZEISS) aspheric IOL. After 1 month monocular and binocular best distance corrected visual acuity (BCVA), uncorrected (UCVA), far corrected at 80 centimeters (intermediate, CIVA) and at 40 centimeters (near, CNVA), defocus curve, contrast sensitivity, optical aberrations and IOL tilting were evaluated

Mean preoperative monocular and binocular visual acuity was 0,52 and 0,68 respectively and raised to 0,99 and 1,16 for UCVA, and to 1,8 and 1,5 for BCVA 1 month after surgery. Monocular and binocular CIVA was 0,56 and 0,64 respectively, whereas CNVA was 0,26 and 0,28. The defocus curve showed values higher than 0.5 up to –2 diopters. The mean scotopic contrast sensitivity was 1.69, 1.86, 1.36, and 0.47 logCS at 3, 6, 12 and 18 cpd. The mean total high order aberration was 0,24 with IOL tilting of 4.7 degrees

The CT LUCIA 621P IOL might seem to give intermediate visual acuity with good contrast sensitivity performance
