Visual Outcomes Of A Toric Trifocal Intraocular Lens Three Months After Cataract Surgery

To evaluate the visual performance in patients with bilateral implantation of a toric trifocal intraocular lens following cataract surgery. 

Hospital Clínico San Carlos. Ophthalmology Department. Madrid. Spain

The research involves 44 individuals who underwent bilateral intraocular lens implantation. The lens under examination was a hydrophobic toric trifocal intraocular lens (Clareon PanOptix Toric, Alcon). Visual results assessed three months after the surgery included monocular and binocular uncorrected distance (UDVA), corrected distance (CDVA), distance-corrected intermediate (DCIVA), and near (DCNVA) visual acuity under photopic conditions. Monocular data correspond to the averages of the right eye.

The mean age was 74.24±8.30 years. The mean value of implanted spherical power of the intraocular lens was 21.25±2.47 D. The 19% of the implanted IOLs had a cylinder up to 1.50D, 21.6% had 2.25D, 35.1% had 3.00D, and 24.3% had 3.75D. The postoperative spherical equivalent was 0.04±0.32 D. Monocular results obtained in the right eye showed a mean of UDVA, CDVA, DCIVA (60cm), and DCNVA (40 cm) under photopic conditions of 0.08±0.08, 0.00±0.05, 0.14±0.10, and 0.16±0.09 logMAR, respectively. Binocular CDVA, DCIVA, and DCNVA were -0.04±0.06, 0.11±0.09, 0.12±0.08 logMAR. The day after surgery, the rotation of the toric lens relative to its position on the day of surgery was 1.65 ± 3.57 degrees, while at 3 months, the rotation was 1.13 ± 3.03 D.

The hydrophobic trifocal toric intraocular lens under study effectively improves distance, intermediate, and near visual acuity in eyes with corneal astigmatism, achieving high values of visual acuity. The prediction of refractive outcomes was highly accurate. Furthermore, the lens has demonstrated excellent rotational stability three months post-surgery.
