Is there a need to check before femtosecond surgery?

Femtosecond surgery is an ophthalmic surgery used to correct myopia, hyperopia and astigmatism. Before femtosecond surgery, doctors usually require patients to carry out a series of examinations to ensure the safety and effectiveness of the surgery.

Corneal topography

Corneal topography is an essential examination in femtosecond surgery. Through corneal topographic map examination, doctors can understand the patient's corneal shape, curvature, thickness and other parameters to determine the feasibility of surgery and develop personalized surgical program. Corneal topography examination usually uses a professional corneal topography instrument. Patients only need to put their eyes on the equipment, and the instrument will automatically record corneal data.

In addition to corneal topography examination, doctors may also conduct wave front examination, fundus examination, etc. to comprehensively assess the eye condition. Through these examinations, doctors can know whether the patient has other eye diseases or potential problems to determine the indications and risks of surgery.

Preoperative ophthalmic examination

The purpose of preoperative ophthalmic examination is to determine whether the patient meets the surgical requirements and the feasibility of surgery. These examinations usually include vision measurement, intraocular pressure measurement, fundus examination, etc.

First of all, measuring vision is an important indicator to evaluate the health of patients' eyes. The doctor will ask the patient to take a vision test, such as a common visual acuity chart, to understand the patient's vision level and whether there are other eye problems.

Secondly, intraocular pressure measurement is an important method to evaluate whether patients have glaucoma. Glaucoma is a chronic eye disease that causes damage to the optic nerve. If the patient's intraocular pressure is too high, it may affect the safety of surgery.

*After that, the fundus examination can understand the health of the patient's retina and fundus blood vessels. Femtosecond surgery has high requirements for retina and fundus blood vessels, so doctors will judge whether patients have potential eye diseases or lesions through fundus inspection.

Preoperative medical history investigation and preoperative consultation

Before femtosecond surgery, doctors will also conduct medical history investigation and preoperative consultation for patients. The medical history survey is mainly to understand the patient's health status, medication and allergy history, so as to evaluate the safety of the operation. Preoperative consultation is to inform patients of the details of the operation, precautions and postoperative care, so as to ensure that patients fully understand and prepare for the operation.

Before femtosecond surgery in a hospital, patients need to undergo a series of examinations. Corneal topography examination is an indispensable item before surgery. It can provide doctors with information about corneal shape, curvature, thickness and other parameters. In addition, preoperative ophthalmic examinations include vision measurement, intraocular pressure measurement and fundus examination to assess whether the patient meets the surgical requirements. At the same time, doctors will also conduct medical history investigation and preoperative consultation to understand the health status of patients and provide detailed surgical information. The purpose of these examinations and consultations is to ensure the safety and effectiveness of surgery and provide patients with * suitable treatment plans.
