Abstract
BACKGROUND: A phakic intraocular lens (IOL) in the posterior chamber is weighty, changes topography of structures, and can affect ocular fluid dynamics.
AIM: The study aimed to assess the parameters of ocular fluid dynamics after ICL STAAR intraocular lens implantation and their relationship with topography of the phakic intraocular lens position based on ultrasound data.
METHODS: From the general population of 98 patients implanted with ICL STAAR V4 phakic intraocular lens as indicated, 10 patients (18 eyes) with myopia of 5–10 D were randomly selected with their consent to study ocular fluid dynamics. Intraocular pressure was measured using an ocular response analyzer, and corneal-compensated and Goldman intraocular pressure was recorded. Tonography was performed using GlauTest-60. Outflow facility (C) and Becker ratio were calculated. Ultrasound was performed using Aviso Quantel Medical with a 50 MHz high-resolution (linear technology) and Clear Scan scleral probe. Visits were planned before surgery and 3 months post-operatively.
RESULTS: Corneal-compensated intraocular pressure was 14.86 ± 2.63 preoperatively and 13.12 ± 3.64 mmHg 3 moths postoperatively; Goldman intraocular pressure changed from 13.12 ± 3.64 to 13.38 ± 3.90. Pre- and postoperative true intraocular pressure (P0) was 13.3 ± 5.60 and 11.75 ± 1.99 mmHg, respectively. Pre- and postoperative outflow facility was 0.23 ± 0.08 and 0.22 ± 0.07 mm3/min•mmHg, respectively. Pre- and postoperative Becker ratio was 52.64 ± 31.59 and 58.81 ± 21.87, respectively. All parameters did not differ significantly after surgery.
CONCLUSION: Ocular fluid dynamics do not change considerably after implantation of posterior chamber phakic intraocular lenses (ICL STAAR V4c). This can be explained by the optimal design parameters and lens shape, which create a synergistic effect of its elements with multidirectional tension from the fixation point in the iris to the fulcrum in the ciliary body.
