Abstract
PURPOSE
Report on the safety, efficiency and refractive outcomes of LASIK surgery in patients aged 65 or older.
METHODS
This study includes a case series of patients ≥65 years that underwent corneal refractive surgery during the period June 2010 to June 2015 at Hospital Zambrano Hellion, Monterrey, Mexico. Inclusion criteria were normal topography, central corneal thickness >500 μm, preoperative manifest refraction spherical equivalent (MRSE) up to -8.5 D and +6.0 D, cylinder up to -6.0 D, CDVA of 20/25 or better and with no other ocular pathology.
RESULTS
A total of 44 eyes (24 patients) were included. Mean age was 67.2 ± 2.1 years (range 65-80), with mean follow-up of 12.2 ± 1.3 months. Conventional LASIK was performed in 20 patients (group 1, 36 eyes) to improve UDVA (10 eyes myopic LASIK and 26 eyes hyperopic LASIK) and presbyopic LASIK (monovision) in 4 patients (group 2, 8 eyes) to restore near-vision performance. Preoperative MRSE group 1 was myopic: -2.79 ± 1.88 D; hyperopic +2.19 ± 1.88 D; and +2.10 ± 0.87 D in group 2. Preoperative UDVA in group 1 was 0.67 ± 0.30 LogMAR; 0.46 ± 0.18 LogMAR; and Jaeger ≥4 in 90% in group 2. Postoperative MRSE: -0.29 ± 0.86 D (myopic LASIK) (p < 0.001), +0.34 ± 0.62 D (hyperopic LASIK) (p < 0.001) and -1.25 ± 0.59 D (non-dominant eye) in presbyopic LASIK. Postoperative UDVA in myopic LASIK was 0.15 ± 0.30 (p = 0.001) and 0.11 ± 0.11 (p < 0.001) for hyperopic LASIK. In group 2, binocular UDVA was 0.16 ± 0.17 (p = 0.12) and UNVA was ≥J2 in 100% of the patients.
CONCLUSION
Even though elder patients may present greater LASIK restrictions due to lens and other ocular age-related changes, patients ≥65 years that were candidates for conventional and presbyopic LASIK showed satisfactory and safe refractive and visual outcomes.
