To describe the patient demographics, endothelial cell(EC) loss and treatment outcomes following phakic collamer intraocular lens(IOL) implantation in a single centre.
A retrospective review of all patients treated for refractive correction with implantation of STAAR phakic collamer IOL between January 2014 and December 2018 at the Mater Private Hospital, Dublin, Ireland was performed.
91 patients and 170 eyes were included for analysis. Mean age was 34.86+-8.74 years. 66% of patients were female and mean follow up was 1.87 years(range 0.1–4.94). Mean preop anterior chamber depth was 3.73+-0.3 mm. Mean preop spherical equivalent(SE) refraction was –9.79+-3.98 Dioptres(D).Mean SE of implanted IOL was -10.52+-3.73D. 55.3% of implanted IOLs were toric.Mean decimal VA at final visit was 0.06+-0.11. Mean EC density at preop assessment was 2836+-177 cells/mm2 and at final review 2739+-201 cells/mm2 with an average loss of 95 cells/mm2. One patient required bilateral IOL explanation due to symptoms of glare. No patient required explantation of IOL due to EC density loss concerns.
In this case series, collamer IOL implantation was noted for its excellent visual outcomes and maintenance of corneal endothelial cell density in patients unsuitable for refractive laser surgery.
