Items of ICL physical examination in Zhongshan Eye Hospital

ICL (Implantable Collimer Lens) is a method of surgically implanting foldable intraocular lens into the eye to correct myopia, hyperopia and astigmatism. Before receiving ICL surgery, patients need to undergo a detailed physical examination to ensure the safety and effectiveness of the surgery. As a professional eye hospital, Zhongshan Eye Hospital will carry out a series of physical examinations before ICL surgery.

Keratometry

Corneal curvature refers to the curvature of the anterior surface of the cornea, which is very important for ICL surgery. Corneal curvature examination is to scan the patient's cornea with professional instruments to obtain detailed data of corneal curvature. This project can help doctors judge whether patients are suitable for ICL surgery and determine the specifications of intraocular lenses required for surgery.

Corneal curvature examination generally includes non-contact measurement of the cornea with automatic corneal topography, and the specific steps include eyedrops of anesthetic eye drops, focusing, image acquisition, etc. This process is very fast and painful. The patient only needs to concentrate on cooperating with the doctor's guidance to complete it.

Fundus examination

Fundus examination is one of the important items to evaluate the patients' eye health. ICL surgery requires normal vision and eye health to ensure the effect of surgery. Fundus examination is mainly used to observe and evaluate the posterior part of the eyeball, including the retina, choroidal blood vessels, and the optic disc, etc. Through fundus examination, doctors can know whether patients have fundus diseases or other abnormalities that affect the operation process.

Fundus examination usually requires pupil dilation. The doctor will drop some special liquid medicine on the patient's eyes to dilate the pupil. Enlarged pupils can provide better vision and help doctors observe the details of the fundus. This process usually causes the patient's vision to be temporarily blurred, but will not cause continuous discomfort.

Intraocular pressure test

Intraocular pressure refers to the pressure inside the eye, which is very important for the health of the eye. Through intraocular pressure examination, doctors can assess whether the patient has glaucoma and other diseases related to abnormal intraocular pressure. For ICL surgery, normal intraocular pressure is one of the prerequisites for safe and successful surgery.

Generally, non-contact tonometer is used for intraocular pressure test. Patients only need to aim their eyes at the instrument and keep their eyes still according to the doctor's instructions. This process is completely painless, very simple and fast.

Preoperative comprehensive evaluation

In addition to the specific items mentioned above, Zhongshan Eye Hospital will also conduct a comprehensive preoperative evaluation. This assessment is based on the patient's personal condition, including age, vision, corneal curvature, fundus and other data, to determine whether it is suitable for ICL surgery. The doctor will give professional suggestions according to the results of the comprehensive assessment, so that patients can understand the risks and effects of the operation.

In conclusion, the physical examination items of Zhongshan Eye Hospital for ICL surgery include corneal curvature examination, fundus examination, intraocular pressure examination and preoperative comprehensive evaluation. These physical examination items can not only help doctors judge whether patients are suitable for ICL surgery, but also ensure the safety and effectiveness of surgery.
