Dalian He's Eye Hospital: How do ophthalmologists choose appropriate laser surgery methods?
Laser surgery is a common ophthalmic surgery, which can effectively correct eye problems and improve the quality of vision. However, different laser surgery methods are suitable for different eye problems. In Dalian He's Eye Hospital, after professional training and rich experience, ophthalmologists can choose appropriate laser surgery methods according to the specific conditions of patients.
Selection basis of ophthalmologist
When opting for laser surgery, ophthalmologists will first consider the patients' eye conditions and vision problems. They will perform a detailed eye examination, including measuring corneal thickness, pupil diameter and other indicators, to assess whether the patient is suitable for laser surgery. If the patient's corneal thickness is insufficient or the corneal shape is abnormal, the ophthalmologist may recommend other surgical methods or treatments.
Secondly, ophthalmologists will also consider the lifestyle and needs of patients. Different laser surgery methods have different postoperative recovery period and effect duration. If the patient requires a short postoperative recovery period, or wants to obtain long-term stable vision, the doctor will choose according to these needs.
Finally, the ophthalmologist will also consider the age of the patient and the stability of the eye condition. Generally speaking, people over 18 years old with stable degree are suitable for laser surgery. For patients who are older or whose degree is still changing, doctors may choose other treatments.
Selection of laser surgery methods
In Dalian He's Eye Hospital, ophthalmologists can choose the following common laser surgery methods according to the specific conditions of patients:
1. Excimer laser (PRK)
PRK is suitable for patients with insufficient corneal thickness or abnormal corneal shape. This operation can correct vision problems by removing cells from the upper layer of the cornea and changing the curvature of the cornea. The recovery period of PRK surgery is relatively long, which takes several days to several weeks.
2. Laser keratomileusis (LASIK)
LASIK is suitable for patients with normal corneal thickness. In this operation, a corneal flap is made, and laser is used to remove or change the shape of the underlying corneal tissue, and then the corneal flap is reset to correct vision problems. The recovery period of LASIK is relatively short, about several days.
3. Femtosecond laser keratomileusis (FS-LASIK)
FS-LASIK is an improved LASIK method, which uses femtosecond laser instead of traditional keratomileusis tool to make corneal flap. The advantage of FS-LASIK surgery is that the corneal flap is made more accurately and the postoperative vision is more stable. The recovery period is similar to that of traditional LASIK.
4. Laser epithelial excimer therapy (TransPRK)
TransPRK is a laser surgery method that does not require corneal incision and corneal flap making. It directly acts on the upper epidermis of the cornea through laser to remove the irregular epidermis, thus correcting vision problems. The recovery period of TransPRK surgery is relatively long, which takes several days to several weeks.
Summary
The ophthalmologists of He's Eye Hospital in Dalian will comprehensively consider the patient's eye conditions, vision problems, lifestyle and needs, age, stability of eye conditions and other factors when choosing laser surgery. According to the specific conditions of patients, they can choose appropriate laser surgery methods, including PRK, LASIK, FS-LASIK and TransPRK. These surgical methods have good results in correcting vision problems, and patients can also obtain satisfactory vision recovery after surgery.
