Intraocular Pressure After Implantation of a Phakic Collamer Intraocular Lens With a Central Hole.
Journal of Refractive Surgery 2017 April 2
PURPOSE: To investigate the middle-term intraocular pressure (IOP) results after implantation of a posterior chamber collagen copolymer phakic intraocular lens (IOL) (V4c Visian; STAAR Surgical Co., Nidau, Switzerland) with a central hole in patients with myopia.
METHODS: This retrospective study enrolled patients who had implantation of a phakic IOL with a central hole. IOP, central vault, and adverse events were evaluated 1, 3, 6, 12, and 24 months postoperatively.
RESULTS: The study enrolled 763 eyes (384 patients, 128 men and 256 women). Mean follow-up was 7.0 ± 7.2 months (range: 1 to 24 months). The mean IOP was 13.2 ± 2.1 mm Hg preoperatively. Postoperatively, the mean IOP was 12.4 ± 1.7 mm Hg at 1 month, 12.5 ± 1.8 mm Hg at 3 months, 12.6 ± 1.3 mm Hg at 6 months, 12.6 ± 1.4 mm Hg at 12 months, and 12.7 ± 1.1 mm Hg at 24 months. Only one case (0.13%) presented an increased IOP (> 21 mm Hg) during the observation period. No pupillary block or acute angle closure was recorded. IOP at the final follow-up visit was 12.8 ± 1.3 mm Hg.
CONCLUSIONS: Implantation of central hole phakic IOL in myopic patients provided good and safe IOP outcomes throughout the 24-month observation period. [J Refract Surg. 2017;33(4):244-249.].
