Ophthalmic surgery is a professional and complex medical technology. Common operations include cataract surgery, corneal transplantation, refractive surgery, etc. Before performing ophthalmic surgery, patients need to understand the risks and precautions related to surgery, so as to make wise decisions and make preparations before surgery.
Risks and precautions of cataract surgery
Cataract is the eye turbidity caused by the decrease of lens transparency, which can be treated by surgery. However, cataract surgery is not without risks. Specific risks include:
1. Infection risk: The surgical incision is easy to be infected, which may lead to eye infection after surgery. After the operation, it is necessary to strictly follow the doctor's medication and nursing guidance, and timely detect and treat the infection.
2. Postoperative intraocular pressure rise: intraocular pressure rise may occur after surgery. Close attention should be paid to the intraocular pressure and corresponding measures should be taken according to the doctor's suggestions.
3. Sequela and complications: In some cases, the operation may lead to decreased vision, blurred vision, corneal edema, etc. The complications include iritis, vitreous hemorrhage, etc.
Before cataract surgery, patients need to regularly check their eye health and evaluate the indications for surgery. Before operation, the doctor shall be informed of his own disease history, drug allergy history and medication situation, as well as the provisions on fasting, water and drugs before operation.
Risks and precautions of corneal transplantation
Corneal transplantation is to replace damaged corneal tissue with healthy donor cornea to treat corneal diseases and restore vision. However, corneal transplantation also has certain risks and precautions:
1. Graft rejection: The transplanted cornea may be rejected by the host's eyeball after surgery, with red, swollen, painful and other uncomfortable symptoms. Long term use of immunosuppressants is needed to prevent rejection after surgery.
2. Postoperative infection: The surgical incision is easy to be infected, and postoperative hygiene should be paid attention to. Nursing should be carried out in strict accordance with the doctor's medication and nursing guidance.
3. Postoperative intraocular pressure rise: The intraocular pressure may rise abnormally after the operation. Close attention should be paid to the intraocular pressure and measures should be taken according to the doctor's guidance.
Before corneal transplantation, patients need to undergo a comprehensive eye examination to evaluate the indications of the surgery and the suitability of donors. Patients need to understand the process of surgery and the requirements of postoperative rehabilitation, and fully communicate with doctors.
Risks and precautions of refractive surgery
Refractive surgery is an operation to correct refractive errors such as myopia, hyperopia and astigmatism by laser to improve vision. The following risks and precautions exist in refractive surgery:
1. Risk of complications: dry eyes, vision fluctuation, increased sensitivity and other complications may occur after surgery. Some complications may gradually reduce or disappear with time.
2. Postoperative vision maintenance problem: vision may decline with age after surgery, and it may be necessary to wear glasses or use contact lenses for vision correction.
3. Preoperative evaluation: comprehensive eye examination and evaluation are required for surgery, including corneal thickness, pupil size and other factors. The doctor should be informed of some health conditions and medication before operation.
Before refractive surgery, patients need to undergo a comprehensive preoperative assessment and examination, including corneal topography, corneal thickness measurement, etc. Patients need to fully understand the effects and limitations of surgery, and cooperate with doctors to decide whether surgery is suitable.
Summary
Before choosing ophthalmic surgery, patients should have a deep understanding of the risks and precautions of surgery, and fully communicate with doctors. Cataract surgery, corneal transplantation and refractive surgery are common ophthalmic operations, and each operation has certain risks and precautions. Through accurate preoperative evaluation and precise surgical operation, combined with postoperative recovery nursing and regular reexamination, the surgical risk can be greatly reduced and good curative effect can be achieved.
