Changjiang Daily, Wuhan Client, May 9th (Reporter Wu Ye, Correspondent Gu Junfang) Although myopia surgery has been widely accepted by the public, it is not for everyone. Recently, 30-year-old Xiao Zhang wanted to remove the thick lenses through surgery, but the inspection found that the eye conditions did not meet the requirements, and it was difficult to “remove the lenses”.

Xiao Zhang lives in Jiangxia District, with 650 degrees of myopia in his left eye and 675 degrees of myopia in his right eye. Seeing that friends successfully got rid of the trouble of glasses after myopia surgery, Xiao Zhang was envious. Recently, he entered the refractive surgery department of Wuhan Purui Eye Hospital with high hopes. Unexpectedly, after a detailed preoperative examination, it was found that the corneal thickness of his eyes was only 475 microns, which was not suitable for laser myopia surgery.
“Myopia surgery is divided into two categories.” Professor Shen Zhengwei, president of the hospital, introduced that one is laser myopia surgery, which achieves correction by cutting the cornea “subtraction”; the other is ICL intraocular lens implantation Enter the surgery, through the “addition”, a miniature “contact lens” is implanted in the eye to achieve myopia correction.
Xiao Zhang’s cornea is too thin and is not suitable for laser myopia surgery, so can it be added? The doctor actively tried to find a way for Xiao Zhang to “take off the mirror”, but to everyone’s dismay, the depth of the anterior chamber of the eye is required to be more than 2.8 mm for ICL implantation, and the depth of the anterior chamber of Xiao Zhang’s eyes is only 2.6 mm, which is not enough to place the ICL artificial lens. crystal. In desperation, Xiao Zhang had to give up the idea of surgery and still use glasses to correct myopia.

“Myopia surgery has strict contraindications and cannot be done with force.” Professor Shen Zhengwei introduced active eye inflammation, glaucoma, keratoconus, severe dry eye, and fundus lesions etc., or diabetes, severe systemic immune diseases, etc., are not suitable for myopia surgery. In addition, corneal thickness, anterior chamber depth, endothelial cell count, etc. are also key indicators for preoperative evaluation. Before surgery, patients need to undergo more than 20 detailed preoperative examinations, and specialists will give specific treatment recommendations based on the results of the examinations.
