Anterior Chamber Angle Width And Intraocular Pressure Changes After Implantable Phakic Contact Lens

Background: The posterior chamber phakic intraocular lens is an effective treatment for high myopia, but it may cause unwanted side effects like increased ocular pressure and cataracts. An affordable equivalent is the implantable phakic contact lens (IPCL).Aim of work: This study evaluates the angle of the anterior chamber and intraocular pressure (IOP) prior to and subsequent to IPCL V2.0 insertion to assess its safety and efficacy.Patients and Methods: In this case series, a prospective investigation included thirty eyes from twenty-one participants with moderate to high myopia who received IPCL V2.0 implantation. Preoperative and postoperative evaluations focused on best corrected visual acuity (BCVA), spherical equivalent (SE), IOP, anterior chamber angle width (ACAW), anterior chamber volume (ACV), and endothelial cell density (ECD) at one, six-, and nine-months post-surgery.Results: BCVA (decimal) improved from 0.35 to 0.50 (P<0.001), and SE changed from -13.98 to -0.34 diopter (D) (P<0.001). ECD decreased from 3307.17 to 3216.70 (P<0.01). IOP peaked at one week but normalized by six months. The ACAW decreased from 54.37° to 29.20° (P<0.01), and ACV dropped from 153.13 mm³ to 108.40 mm³ (P<0.001).Conclusions: The implantation of Intraocular Phakic Contact Lenses is a secure and adequate procedure for correcting average to high myopia, especially when corneal refractive surgery is not suitable. Although changes in the anterior chamber and increased intraocular pressure were noted initially post-surgery, these parameters stabilized over time during extended monitoring.
