Postoperative Outcomes Of Toric Intraocular Lens Implantation In Patients Aged Over 85 Years

This study aims to assess the postoperative outcomes of toric intraocular lens (T-IOL) implantation in cataract surgery patients aged over 85 years.

Ryugasaki Saiseikai Hospital, Ibaraki, Japan

We conducted a retrospective review of 30 eyes from 17 patients aged over 85 (mean age: 88.5±4.1 years) with preexisting astigmatism (0.75D to 3.52D) who received cataract surgery with T-IOL implantation. Preoperative astigmatism was measured using anterior segment optical coherence tomography (CASIA2® Tomey, Japan), with axis marking by a digital guidance system (VERION® Alcon, USA). Phacoemulsification was performed through a 2.2mm corneal incision at 12 o'clock. Postoperative assessments at 3 months included UDVA (logMAR), astigmatism, and IOL axis misalignment. Results were compared with 30 eyes of 15 younger patients (mean age: 73.9±8.6 years) who underwent the same procedure.

There were no statistically significant differences in preoperative parameters between the two age groups, except for age and UDVA logMAR (p<0.001 each). Postoperatively, there were no statistically significant differences observed in mean UDVA logMAR (0.00 for the >85 age group and -0.05 for the younger age group, p=0.17), postoperative astigmatism (0.21D vs. 0.16D, p=0.33), or IOL axis rotation (1.97° vs. 1.43°, p=0.14) between the two groups.

Implanting T-IOLs in patients over 85 years of age, when performed using appropriate surgical techniques, can achieve postoperative outcomes comparable to those observed in younger patients.
