Expert consensus on standardized practice for preoperative examination for posterior chamber phakic intraocular lens implantation (2023)

Currently, posterior chamber phakic intraocular lens implantation is widely used in clinical practice, and its safety, efficacy and stability have been clinically validated.As an intraocular procedure, there are potential risks during and after surgery.Preoperative evaluation is crucial to prevent complications and ensure the safety of the procedure.This consensus provides recommendations for preoperative evaluation based on key national and international literature and evidence-based research.In addition to routine ocular examinations, the following are essential: dominant eye, manifest refraction, corneal thickness, corneal curvature, corneal horizontal white to white, sulcus to sulcus, anterior chamber depth, lens thickness and crystalline lens rise, pupil diameter and scotopic pupil size.Due to the high demands on postoperative outcomes and visual quality in patients undergoing refractive surgery, additional ocular examinations may be included depending on the patient’s condition: visual quality, dry eye, and visual function.The purpose of this consensus is to standardize the preoperative examination for posterior chamber phakic intraocular lens implantation in order to provide reference and assistance to ophthalmologists in this area.
