Purpose
To assess the incidence and causes for retreatment following monovision laser refractive surgery in a large data study spanning over a decade.
Setting
Care-Vision Laser Centers
Methods
This retrospective study included patients aged 36-60 years who underwent monovision laser vision correction at the Care-Vision Laser Centers, Israel from January 2012 to December 2022. Demographic, pre and postoperative data were retrieved for analysis.Overall, 3674 eyes of 1847 patients were included with retreatment performed in 1.28% of eyes, 0.84% distant-targeted and 0.44% near-targeted.
Results
Monovision reversal in near targeted eyes occurred due to over-myopia (37.5%, n=6/16), despite being on target (25%, n=4/16), insufficient myopia (18.8%, n=3/16), and de novo astigmatism (12.5%, n=2/16). One eye was aimed for near vision due to de novo astigmatism. Retreatment in distance-targeted eyes was due to myopic undercorrection (45.2%, n=14/31), myopic regression (19.4%, n=6/31), myopic overcorrection (12.9%, n=4/31), hyperopic regression (6.5%, n=2/31), astigmatism undercorrection (6.5%, n=2/31), de novo astigmatism (6.5%, n=2/31) and astigmatism regression (3.2%, n=1/31). Retreatment was more likely in distance versus near targeted eyes of monovision patients (p=0.025) and non-monovision patients (p<0.001).
Conclusions
In monovision laser vision correction, retreatment in the near targeted eye is rare when the ideal near target (-1.50 to -1.25D) is achieved. However, the distance targeted eye is more likely to require retreatment. Surgeons can plan monovision surgery and advise patients accordingly.
