Sequelae and risk of laser surgery for myopia

Abstract: keratoconus can only be treated by corneal transplantation. The postoperative visual acuity can reach 1.0. The visual acuity mainly depends on the suture skills, rejection and other factors., The sequelae of myopia laser surgery. Every operation without good health care will leave sequelae. What are the sequelae of myopia laser surgery? Xiaobian will tell you about the sequelae of laser surgery for myopia., The sequelae of myopia laser surgery, the first dry eye, is a very difficult eye disease. The current treatment is also some symptomatic myopia surgery, which can not be fundamentally solved., Second, complicated with severe keratitis, such as viral keratitis, corneal transplantation is needed when it is the most serious, which is a more serious sequelae. We must not trifle., Third, the eyesight returns to the original state or slightly better.,

myopia laser surgery sequelae, each operation without good health care will leave sequelae, so what are the sequelae of myopia laser surgery? Xiaobian will tell you about the sequelae of laser surgery for myopia.

sequelae of myopia laser surgery

first dry eye syndrome

this is a very difficult eye disease. The current treatment is also some symptomatic myopia surgery, which can not be fundamentally solved.

the second complication is severe keratitis

. For example, corneal transplantation is needed when viral keratitis is the most serious. This is a more serious sequelae. We must not trifle with it.

third vision fallback

fallback to the original state or slightly better.

after the fourth operation, corneal flap dehiscence was caused by accidental collision,

complicated with a series of serious complications.

the fifth keratoconus

can only be treated by corneal transplantation. The postoperative visual acuity can reach 1.0. The visual acuity mainly depends on the suture skills, rejection and other factors.

3. Patients’ full ideological preparation and active cooperation during and after operation are another important link to ensure the success of the operation. If the ideological preparation is insufficient, the intraoperative tension is too tight, or the head is moved, complications can occur.

4. The operator should have rich microsurgical experience, undergo strict microsurgical training, be familiar with the microsurgical instruments used for the operation, be familiar with the conditions of all kinds of ametropic cornea and eyeballs, be able to deal with all kinds of unexpected situations during the operation, properly deal with all kinds of problems, and prevent and reduce the occurrence of complications.

5. Effective retrobulbar anesthesia is an important link to ensure the success of the operation. Inadequate anesthesia, intraoperative pain, orbicularis oculi muscle contraction and eye movement will cause accidental complications.

6. Preoperative examinations should be accurate, such as the measurement of corneal curvature and corneal thickness, mydriatic optometry to determine the diopter, etc. these examinations should be very accurate, otherwise there will be great differences in the calculation of operation volume, incision depth and quantity, and complications such as too deep incision, corneal perforation and irregular astigmatism are easy to occur during the operation.

operation risk the safety of

laser correction operation is related to the operation experience and equipment of doctors. Surgery is not zero risk, mainly to avoid two postoperative complications. Any corneal surgery has a wound, there will be a chance of infection. Some of the sequelae of myopia surgery are exposed to the air after corneal recovery. If you don’t pay attention to hygiene, it will cause inflammation and infection.

and

in the treatment of myopia is to flatten the cornea, but the too flat cornea will be squeezed by the pressure from the inside of the eye and make the cornea bulge forward. This pressure can not be felt, but the consequence is that not only there is no treatment for myopia, but it will aggravate myopia and even produce irreversible astigmatism.

the first

causes the sequelae of myopia surgery because there is no strict and careful exclusion before surgery, so we’d better choose professional medical institutions for treatment.

the second

is that although qualified patients are screened out, the surgical scale is not appropriate when doctors operate. For example, a certain corneal thickness should be retained, but some doctors want to completely correct the vision of patients with high myopia and cut the cornea too thin, resulting in adverse consequences.
