Purpose: Assess refractive results and patient satisfaction in presbyopic myopes and hyperopes after PresbyMAX® Symmetric multifocal ablation profile over a five-year period.
Methods: This retrospective observational cross-sectional study analyzed 82 eyes from 41 patients from the period of December 2014 to August 2017. All patients were examined preoperatively to obtain baseline measurements. All patients underwent PresbyMAX procedure. Patients were evaluated postop at day one, one week, one and three months, and then yearly for five years. A questionnaire was used to assess outcomes such as glare, halos, night vision, etc.
Results: 82 eyes were included; 22 hyperopes and 19 myopes. Mean age during operation was 45±1.9 (41.8 to 50.2). After five years, the mean post-operative spherical equivalent was significantly higher in hypermetropic patients (0.63 ±0.64; -0.62 to 1.75) compared to myopes (0.12 ±0.61; -0.75 to 1.13) (P=0.011). The mean post-operative UDVA and CDVA were significantly better among hyperopes (0.27 ±0.17; 0 to 0.6 and 0.13 ±0.11; 0 to 0.3 respectively) compared to myopes (0.39 ±0.14; 0.1 to 0.6 and 0.26 ±0.1; 0.1 to 0.4 respectively). There was no difference in the safety index between hyperopes (0.99±0.06; 0.85 to 1.17) and myopes (0.99±0.06; 0.94 to 1.06) (P value 0.986). The satisfaction analysis after five years revealed that the mean patient satisfaction after five years was 70% for both groups. Hyperopes had slightly better means for near vision, halos, glare, and night vision satisfaction.
Conclusion: Aspheric PresbyMAX Symmetrical is a safe and effective procedure for correction of presbyopia in myopes and hyperopes.
