Abstract

Purpose: The current study investigates the effect of hyperopic Orthokeratology lenses (Boston Xo) in correction of Presbyopia based on the Monovision technique. Methods: This is a clinical trial study. Eleven individuals (have been recruited for this study, after meeting the inclusion and exclusion criteria. The initial examinations were carried out for ordering the contact lenses. After complete training of how to use the contact lens, fluorescein pattern was evaluated for centrality and proper fitting. Participants were asked to wear the lens for seven nights on the non-dominant eye. In the morning of 1th and 7th days, one hour after the lens removal, examinations were repeated. We conducted the initial examination and repeated them in day one and day seven after use of the lens and after one week wash out, in day fourteen. The changes in refraction, visual acuity, corneal thickness and corneal curvature were evaluated. Analysis was performed using the analysis method of variance with duplicate measurement and Bonferroni follow-up test at the error level of 5% with use of SPSS version 24. Results: Statistical population of this study was include of people between 43-50 years old, without any problem in visual acuity for distance that need correction for near. In tested eye, central thickness of the cornea was increased in 1th and 7th day. Also the central curvature were steeper and the peripheral curvature were flatter and the amount of myopia were increased. These changes were significant in 1th and 7th days and return to initial amount in 14th day. Conclusion: Hyperopic Orthokeratology lenses (Boston Xo) could be considered as an option for correction of Presbyopia in Monovision technique.
