Purpose: In this case report, we report visual function and dynamic accommodation changes after implantation of monofocal intraocular lenses (IOLs) for cataract surgery in the first 6 months post-surgery.
Methods: A 48-year-old man was diagnosed with bilateral anterior subcapsular cataract. After cataract surgery, monofocal IOLs of different powers for the right (RE) and left eye (LE) were implanted for monovision. During a 6-month follow-up period.
Results: The distance visual acuity (VA) remained over 1.0 for the RE and near VA remained over 0.8 for the LE. Dynamic accommodation of approximately 0.25 D to 0.50 D was observed with an accommodative stimulus.
Conclusions: Monovision with monofocal IOLs may provide decent visual function. Although stereopsis may be a disadvantage with monovison, prescribing a progressive addition lens can be an alternative to compensate for decreased visual function. In addition, this case report demonstrated dynamic accommodation with accommodative stimuli despite monofocal IOLs. Therefore, it is important to understand the optical refractive error changes that occur in pseudophakia, and how the effects may change with age.
