Corneal collagen cross-linking (CXL) by Mazen M. Sinjab is a specialized procedure designed to strengthen the cornea, particularly in patients with keratoconus or corneal ectasia. This technique involves the application of riboflavin (vitamin B2) drops to the cornea, followed by exposure to ultraviolet (UV) light. The riboflavin absorbs the UV light, initiating a photochemical reaction that creates covalent bonds between collagen fibers within the corneal stroma. This cross-linking process increases the mechanical stability and rigidity of the cornea, reducing the progression of ectatic diseases and improving visual acuity in many patients. Sinjab's approach emphasizes a meticulous technique to optimize the effectiveness and safety of the procedure, including careful patient selection and preoperative assessments. Postoperatively, patients may experience varying degrees of discomfort and visual fluctuations, but many report significant improvements in their condition over time. The overall goal of corneal collagen cross-linking is to halt disease progression, ultimately allowing patients to maintain functional vision and delay or prevent the need for corneal transplantation. As a minimally invasive option, CXL has gained popularity among ophthalmologists and patients seeking to manage corneal diseases effectively.
