Abstract Details

Purpose:

To assess short-term refractive and visual outcomes of presby-LASIK in the treatment of presbyopia.

Setting:

Wollongong Refractive Laser Eye Institute, Wollongong, Australia

Methods:

Retrospective observational case series of 27 eyes from 14 patients (50% female, average age 54±3.5 years) following treatment with µ-monovision (12 eyes) or monocular (15 eyes) presby-LASIK. Flap creation and ablation was performed using a VisuMax 400Hz femtosecond laser and a Schwind 1050S excimer laser respectively. A plano refractive target was used for distance eyes and -1.25 or -1.5 DS for reading eyes. Predictability and efficacy were assessed 4-6 weeks, and safety and spectacle independence 3 months following surgery.

Results:

Average spherical equivalent (SE) improved from 1.19±0.1 D preoperatively to -0.12±0.44 D and -1.2±0.67 D at 4-6 weeks postoperatively for distance and near eyes respectively; 96% of eyes achieved SE ±1 D of the target. Postoperative binocular uncorrected UDVA, UIVA and UNVA were 0.0±0.13 LogMAR, -0.05±0.12 LogMAR and 0.24±0.07 LogMAR under photopic and 0.0±0.11 LogMAR, 0.26±0.13 LogMAR and 0.61±0.12 LogMAR under mesopic conditions respectively. 79% of patients achieved binocular UDVA of 20/20 or better, and 11% lost 1 or more line of BCVA. One patient required reading spectacles following surgery.

Conclusions:

Presby-LASIK gave good results in the treatment of presbyopia with a high level of predictability and efficacy with most patients achieving full spectacle independence. Intermediate and near vision may be compromised under low light conditions and dry eye may slow recovery of BCVA. Similar outcomes were achieved for monocular and µ-monovision treatments.
