Purpose
To evaluate the ophthalmologic outcomes of presbyopic patients who depended on glasses and underwent PresbyLASIK, focusing on improvements in both distance and near visual acuity.
Setting
All patients underwent a complete ophthalmologic exam before surgery, including visual acuity (with and without correction), Jaeger test, biomicroscopy and retinal mapping. Patients with any ophthalmological pathology or contraindications for refractive laser surgery were excluded from the study.
Methods
Thirteen patients (26 eyes) were divided into two groups. Group 1 (G1) included patients with myopic and astigmatism (12 eyes), while Group 2 (G2) included patients with hyperopic and astigmatism (14 eyes). All patients underwent the PresbyLASIK procedure at Hospital de Olhos - CRO, in Guarulhos, São Paulo, Brazil. The mean age was 45 years in G1 and 44 years in G2. The preoperative spherical equivalent (SE) mean in G1 was -3.958 ± 1.656 diopters (D) (-8.375D to -1.75D), with a mean near addition of 1.291D (1.00D to 2.00D). In G2, the preoperative SE mean was 1.946 ± 0.968D (0.125D to 4D), with a near addition of 1.464D (1.00D to 1.75D). The ablation was performed using the Alcon Allegretto laser (Alcon Laboratories, Inc., Fort Worth, TX).
Results
After one month, the spherical equivalent (SE) in G1 was 0.91 ± 0.43D (0.0 to -1.75D), while in G2, it was 0.66 ± 0.59D (-1.75D to 0.625D). Ten patients (77%) achieved an uncorrected visual acuity (UCVA) of 20/20, and 12 patients (92.30%) reached a near UCVA of J1. One patient lost a maximum of one line of best-corrected visual acuity with glasses.
Conclusions
PresbyLASIK demonstrated effective correction of presbyopia in patients with pre-existing myopic or hyperopic astigmatism. The procedure provided significant improvement in both distance and near vision, reducing the need for glasses. While the initial outcomes are encouraging, continued monitoring and further research will help optimize the technique and establish long-term efficacy and safety.
