摘要
Objective: To investigate whether any association exists between apparent accommodation in pseudophakic eyes and multifocal corneal effects. Design: A prospective observational case series. Participants: A total of 121 eyes of 98 patients who had undergone phacoemulsification and posterior chamber intraocular lens implantation were studied. Methods: The amount of apparent accommodation was measured using an accommodometer. The degree of corneal multifocality was determined on the corneal topography by measuring the maximum and minimum corneal refractive powers within the pupillary area. Refractive astigmatism, keratometric astigmatism, pupillary diameter, and age were also analyzed. Main Outcome Measures: Apparent accommodation, corneal multifocality, refractive and keratometric astigmatism, pupillary diameter, and age. Results: Multiple regression analysis revealed that corneal multifocality and pupillary diameter had significant positive correlations with apparent accommodation, whereas other explanatory variables showed no relationship with apparent accommodation. Conclusion: Multifocal corneal effects contribute to apparent accommodation in pseudophakic eyes.
