Summary
Intraocular lens (IOL) dislocation after cataract surgery is rising significantly. This trend necessitates increased awareness and preparedness among eye care practitioners for managing these cases.
Area of Science:
- Ophthalmology
- Surgical Outcomes
- Public Health
Background:
- Cataract surgery is a common procedure worldwide.
- Intraocular lens (IOL) dislocation is a potential complication.
- Longitudinal data on IOL dislocation trends are crucial for understanding evolving risks.
Purpose of the Study:
- To characterize longitudinal trends in intraocular lens (IOL) dislocation following cataract surgery.
- To identify temporal changes in the incidence of IOL dislocation over two decades.
Main Methods:
- Retrospective cohort study utilizing the TriNetX network.
- Analysis of 866,010 patients undergoing cataract surgery (2000-2024).
- Identification of IOL dislocation and associated risk factors using ICD-9/-10 and CPT codes.
Main Results:
- The incidence of IOL dislocation increased significantly from 2020-2024 (1.1% of cases).
- A monotonic increase in IOL dislocation rates was observed over the past two decades (P < .01).
- Concurrent increases in ocular trauma, intravitreal injections, and pars plana vitrectomy rates were also noted (P < .01).
Conclusions:
- Intraocular lens dislocation after cataract surgery is an emerging concern.
- The rising incidence highlights the need for proactive management strategies.
- Ophthalmologists must be prepared for the increasing prevalence of IOL dislocation.
