What is optimized corneal surface cutting surgery and what are its advantages? Optimized superficial corneal cutting surgery is designed to control the healing response of the cornea, corneal subepithelial clouding and refractive fluctuation with technical intervention of the excimer cutting of the corneal surface. It has the advantage, first of all, of avoiding the risk of corneal flaps. A regular LASIK surgical keratome can result in a 2-in-1,000 flap risk of developing surgically-derived astigmatism. It is the nightmare of all refractive surgeons. In contrast, the concern of flap risk caused by a superficial cutting epithelial knife simply does not exist. Second, because the flap is thinner (about 60 microns), the laser cuts the more stable anterior corneal stroma, and postoperative corneal biomechanics are maximized, with less regression and better visual quality. Thirdly, the cornea heals completely after surgery, and there is no possibility of traumatic corneal displacement. It is especially suitable for people who participate in sports regularly. That is why we consider optimal corneal surface cutting surgery first for patients who participate in military recruitment, under the same conditions. Fourth. Because no knife is used, the economic cost is low, with a cost of 6,000 yuan for surgery in both eyes. It also benefits the doctor-patient relationship. In fact, what many refractive surgeons themselves do is safe optimized superficial corneal cutting surgery. Speaking of which. One might ask. If optimized superficial corneal cutting is so good, wouldn’t every patient choose to have it done? Yes. Optimized superficial corneal excision has its own limitations. Its biggest drawback is that it still does not eliminate postoperative pain and discomfort. The repair of the corneal epithelium is a process. The corneal epithelium has to be repaired first with a full wound before it can be restored to a clear and regular state. There is photophobia, tearing and foreign body sensation for 1 to 2 days after the surgery, and it takes about 2 weeks to regain vision. Hormonal eye drops should be used for 3 months after surgery. The frequency of review should be increased accordingly. However, for patients, it is well worth the small price to pay compared to its advantages. In addition, optimal superficial corneal cutting is more demanding on the operator, with the highest principle being to maintain a highly viable corneal epithelial flap. With advances in cutting-edge basic research in ophthalmology and continuous improvements in medications and technical interventions, optimized corneal surface cutting has become increasingly sophisticated. Problems such as subepithelial clouding and hormonal hypertension that originally plagued ophthalmologists have been better addressed. The future of optimized corneal surface cutting surgery is promising.
