Age affects intraocular lens attributes preference in cataract surgery.

PURPOSE

The aim of this study is to analyze the effects of age on intraocular lens (IOL) attributes preference.

MATERIALS AND METHODS

We enrolled 4213 eyes that underwent smooth phacoemulsification and IOL implantation between January 2005 and June 2018. Patients were subdivided into six groups according to their ages, i.e.,≤40, 41-50, 51-60, 61-70, 71-80, and ≥ 81 years old. The difference in preference of IOL attributes regarding age, gender, and year of surgery was analyzed separately. The analyzed IOL attributes included asphericity, astigmatism-correction, presbyopia-correction, and blue-blocking function.

RESULTS

The patients averaged 68.3 ± 11.6 years old at the time of surgery. There was no significant difference in age between males and females. There were 1980 patients (47.0%) selected aspheric IOL, 822 patients (19.5%) selected multifocal (MF) IOL, 93 patients (2.2%) selected toric IOL, and 859 patients (20.4%) selected blue-blocking IOL. Adoption of aspheric and MF IOL increased significantly during the study ( < 0.001 for both attributes). There were more young patients selected aspheric and MF IOL ( < 0.001 for both), and the change in the trend of adoption over the years was also most significant in the young group ( < 0.001 for both). The proportion of patients that selected blue-blocking IOL decreased significantly after 2011 ( < 0.001). There was no gender preference in aspheric, MF, and toric IOL selection. However, there were more male patients selected blue-blocking IOL ( = 0.018).

CONCLUSION

The adoption of IOLs with emerging technologies increased significantly over the years. Younger adults tended to adopt advanced technology IOL more than the older ones.
