Guangzhou Huangpu, Department of Ophthalmology, CUHK: How to treat astigmatism?

introduction

Astigmatism is a common visual problem, which causes the eyes to be unable to focus correctly on objects at short or long distances. The Department of Ophthalmology and Optometry of CUHK is a professional ophthalmic hospital in Huangpu District, Guangzhou. With advanced equipment and an experienced team of doctors, it can provide a variety of methods to treat astigmatism and help patients recover clear vision. This article will discuss the treatment of astigmatism in the optometry department of the department of middle and large ophthalmology from four aspects.

Corneal plastic lens treatment

Corneal shaping lens is a non-invasive method for the treatment of astigmatism. It can change the curvature of the cornea by wearing specially designed hard or soft lenses on the corneal surface to achieve the effect of correcting astigmatism. During the treatment, the doctor will select appropriate lenses according to the patient's eye conditions and symptoms, and gradually adjust the corneal curvature after wearing them for a period of time to improve the patient's vision.

1. Correction of corneal curvature

The main mechanism of keratoplasty lens treatment is to correct the visual problem of astigmatism by changing the curvature of the cornea. According to the specific situation of the patient, the doctor will design appropriate lens curvature to match the curvature of the patient's eye, and adjust the shape of the cornea through appropriate wearing time to improve the patient's vision.

2. Personalized customization

Everyone's eye conditions are unique, so the Optometry Department of CUHK will customize the corneal shaping lens according to the specific conditions of each patient. The doctor will carefully measure the patient's eye data, including corneal curvature, pupil size, etc., to determine appropriate lens parameters, so as to achieve the best treatment effect.

3. Alternatives not suitable for corrective surgery

For some patients who are not suitable for corneal correction surgery, corneal plastic lens treatment can be an alternative. For example, for patients who are younger or whose eye conditions are not suitable for surgery, we can consider using a keratoscope to treat astigmatism to improve vision.

Laser corneal surgery

Corneal laser surgery is another common method for the treatment of astigmatism, which is also widely used in the optometry department of the Department of Ophthalmology of the Middle and University. This surgery changes the shape of the cornea through laser technology, thus correcting the visual problem of astigmatism.

1. Laser removes part of corneal tissue

Corneal laser surgery mainly uses laser to remove part of the tissue on the corneal surface, thus changing its curvature. The doctor will determine the depth and position of the cutting according to the astigmatism degree and eye condition of the patient to achieve the therapeutic effect.

2. Fast and accurate

Corneal laser surgery is a fast and accurate treatment method. The operation time is usually only a few minutes, and the recovery period is short. After surgery, the patient's vision usually improves rapidly, and the effect is stable and lasting.

3. Preoperative detection and evaluation are required

Due to the high requirements of corneal laser surgery on patients' corneas, detailed preoperative detection and evaluation are required. The Department of Ophthalmology and Optometry of CUHK has advanced laser surgical equipment and an experienced team of doctors, who can comprehensively assess the eye conditions of patients and provide personalized surgical solutions for patients.

Correction of glasses or contact lenses

Glasses or contact lenses are a conservative treatment for astigmatism, which can improve the focus of the patient's eyes by adjusting the refraction of light.

1. Correction of glasses

By wearing suitable glasses, the refraction of light can be corrected according to the degree and type of astigmatism to help patients achieve clearer visual effects. Glasses correction is a simple, safe and effective method for astigmatism treatment.

2. Contact lens correction

Contact lenses can also be used to correct astigmatism. Unlike glasses, contact lenses fit on the surface of the eye, which is closer to the natural state of the eye, providing a broader vision and more comfortable experience.

3. Regular review

For patients who choose glasses or contact lenses for correction, regular reexamination is essential. The doctor of the Department of Optometry of CUHK Ophthalmology will conduct regular inspection according to the patient's condition, and adjust the correction method according to the inspection results to ensure the stability of the patient's vision and obtain the best correction effect.

summary

The Optometry Department of the Department of Ophthalmology of CUHK provides a variety of methods for the treatment of astigmatism, including corneal plastic lens treatment, corneal laser surgery and glasses or contact lens correction. Through personalized treatment plan, help patients to improve their vision problems caused by astigmatism and restore clear vision. If you have a problem with astigmatism, you may consider seeing a doctor in the Optometry Department of the Department of Ophthalmology of CUHK, and the professional doctor team will provide you with the most appropriate treatment plan.
