Purpose
With the increasing prevalence of presbyopia in patients without cataracts, there is a growing demand for effective treatment options that address both presbyopia and refractive errors. This study evaluates the long-term efficacy of multifocal phakic intraocular lenses (IOLs) (Implantable Contact Lens, EYEOL, UK) in presbyopic patients, focusing on improvements in visual acuity and patient satisfaction.
Setting
Minoru Tomita Eye Clinic Ginza, Tokyo, Japan
Methods
A retrospective study was conducted on 519 presbyopia patients (1036 eyes) who underwent multifocal phakic IOL implantation. Preoperative and 1-year postoperative measurements of Uncorrected Distance Visual Acuity (UDVA), Uncorrected Near Visual Acuity (UNVA), Uncorrected Intermediate Visual Acuity (UIVA), Spherical Equivalent (SE), and corneal endothelial cell density were statistically analyzed
Results
The mean patient age was 48.57±4.68 years. Preoperatively, the mean UDVA, UNVA, UIVA, and SE were 20/160, J7, 20/80, and -4.01±3.61D, respectively. One year postoperatively, significant improvements were observed: UDVA improved to 20/16, UNVA to J2, UIVA to 20/22, and SE to -0.01±0.44D. No significant changes were detected in corneal endothelial cell density between 3 months and 1 year post-surgery.
Conclusions
Multifocal phakic IOL implantation demonstrated significant improvements in both UDVA and UNVA, providing effective vision correction for presbyopia patients. A high satisfaction rate of 93% was reported, with only 7% expressing dissatisfaction. These findings suggest that multifocal phakic IOLs are a promising long-term solution for presbyopia, enhancing both vision and quality of life.
