Introduction
Whether a patient with -6.00 diopters of myopia is eligible for surgery depends on the preoperative examination results. First, the patient must be over 18 years of age and have demonstrated stable refraction—no more than a 50-diopter change—over the preceding two years. Prior to laser surgery, a comprehensive ophthalmic evaluation is required, including assessment of the retina, intraocular pressure, refractive error, corneal thickness, and corneal curvature. Based on these findings, the surgeon will conduct a thorough safety evaluation of all aspects of the procedure.
Modern life moves at a faster pace, and stress levels are high. Many people neglect their physical health, leading to ocular diseases. Myopia is particularly common and significantly impacts patients’ daily lives—thus requiring special attention. So, can 600-degree myopia be corrected surgically?
Can 600-degree myopia be corrected surgically?
Whether surgical correction is feasible for 600-degree myopia depends on the results of preoperative examinations. First, the patient must be over 18 years of age, and their myopia must have remained stable—within a fluctuation of no more than 50 degrees—over the past two years. Prior to laser surgery, comprehensive ophthalmic evaluations are required, including assessments of the retina, intraocular pressure, refractive error, corneal thickness, and corneal curvature. Based on these findings, the surgeon conducts a thorough safety evaluation of all surgical aspects before making the final decision on whether surgery is appropriate. Generally, conventional laser refractive surgery is indicated for myopia up to approximately 1200 degrees.
Surgical correction is typically viable for 600-degree myopia. This degree falls at the borderline between moderate and high myopia and is widely treated in clinical practice using procedures such as femtosecond laser corneal surgery, excimer laser surgery, and implantable collamer lens (ICL) surgery. For 600-degree myopia, femtosecond or semi-femtosecond laser surgery is generally recommended. Patients considering surgical correction should first visit a reputable optometry center or ophthalmology clinic for relevant eye examinations—including corneal thickness measurement, corneal topography, intraocular pressure testing, and fundus examination. Surgery may only be scheduled for adults aged 18 years or older who demonstrate stable vision, normal ocular surface anatomy, and overall ocular health suitable for the procedure.
Patients are advised to maintain healthy visual habits: avoid prolonged near-work, limit extended use of electronic devices, keep eyes clean, ensure adequate sleep, and seek prompt medical attention if symptoms worsen. We hope this information proves helpful.
