Visual Performance After Unilateral Implantation Of Non-Diffractive Spiral Optic Iol Implantation Intraocular Lens In Patients With Unilateral Cataract.

To investigate the visual performances after unilateral implantation of a non-diffractive spiral optic intraocular lens IOL in patients with unilateral cataracts.

Cornea and refractive surgery department of Quironsalud Hospital Marbella.

In this prospective study, uneventful phacoemulsification with Galaxy (Rayner) IOL implantation was performed in 25 eyes of 25 patients with unilateral cataracts. At postoperative 1, 4, 12 , and 24 weeks, the logarithm of the minimal angle of resolution of uncorrected and corrected visual acuity at far, intermediate, and near distances and the spherical equivalent in manifest refraction were measured. A PROMS questionnaire was used to investigate glare, spectacle dependency, and satisfaction at 24 weeks in the operated eye. All of these patients were spectacle-dependent for near and intermediate vision before cataract surgery.

At 6 months, uncorrected distance visual acuity achieved 0.0 LogMAR in 96% of cases, distance corrected intermediate visual acuity (DCIVA) achieved 0.0 LogMAR in all cases (60cm), and distance corrected near visual acuity (DCNVA) achieved 0.1 LogMAR in 92 % of cases (40 cm). The patient’s satisfaction score was 100 % based on PROMS questionnaire for far, intermediate, and 92% for near distance, respectively. No patients complained of the permanent photic phenomenon.

 No patients reported bilateral imbalance due to unilateral surgery.

The unilateral implantation of this non-diffractive spiral optic seems to be tolerated and effective in improving the visual function of patients with unilateral cataract with limited optical side effects such as haloes or glare, providing spectacle-independent vision from far to intermediate object distances.
