Overview of laser correction ophthalmic surgery
Laser correction ophthalmic surgery is a common method to treat myopia, hyperopia and astigmatism. The corneal tissue is remodeled by laser to change the refraction of the eyeball, so as to achieve the purpose of correcting vision. LASIK and PRK are two main methods of laser correction ophthalmic surgery.
LASIK is one of the most widely used laser surgery. It uses a laser cutting device to make a thin flap on the upper part of the cornea, then uses a laser to reshape the corneal tissue, and finally puts the flap back in place.
PRK surgery is an earlier and traditional laser correction surgery. It completely removes the corneal epithelium, and then uses laser to reshape the corneal tissue. Compared with LASIK, PRK has a longer recovery time, but it is suitable for some special eye conditions.
Effect and risk of laser correction ophthalmic surgery
Laser correction ophthalmic surgery can significantly improve the vision problems of myopia, hyperopia and astigmatism. Most patients can significantly reduce their dependence on glasses or contact lenses after surgery and recover to a good vision level.
However, laser orthopaedic ophthalmic surgery also has some risks and side effects. Inaccurate preoperative evaluation may lead to surgical failure or poor vision, and may also cause dry eyes, vision fluctuations, light interference and other uncomfortable symptoms. Although these complications rarely occur, they still need to be fully consulted and evaluated before the operation to ensure the safety and feasibility of the operation.
Applicable population of laser correction ophthalmic surgery
Laser correction ophthalmic surgery is applicable to myopia, hyperopia and astigmatism patients over 18 years old. For myopic patients, the refractive range of surgery needs to be within a certain range to ensure the effect and safety of surgery. In addition, laser correction ophthalmic surgery requires a certain degree of corneal thickness, corneal shape and eye surface health.
For some special cases, such as women in pregnancy or lactation, patients with keratopathy and patients with autoimmune diseases, laser correction ophthalmic surgery should be carefully considered, and doctors should evaluate and make decisions according to the specific situation.
Can glasses be completely removed in laser correction ophthalmic surgery
Laser corrective ophthalmic surgery can remove glasses to a certain extent, but not completely. The effect of surgery varies from individual to individual. Some people may have unstable vision after surgery or need to wear low-grade lenses for correction. In addition, surgery can only correct refractive problems such as myopia, hyperopia and astigmatism, and cannot solve other eye diseases or problems.
Therefore, although laser corrective ophthalmic surgery can significantly reduce dependence on glasses, glasses cannot be completely removed. Before considering the operation, patients should fully understand the effect and risk of the operation, and conduct detailed consultation and communication with doctors to determine the applicability and expected effect of the operation.
Summary
Laser correction ophthalmic surgery is a common method to treat myopia, hyperopia and astigmatism, which can significantly improve vision problems. The effect and safety of the operation need to be fully evaluated and consulted before the operation. Surgery can not remove glasses completely, but it can reduce the dependence on eye correction tools to a certain extent. Before deciding to perform surgery, patients should clarify the scope of application and effect of surgery to make rational decisions.
