Xiangyang First Hospital femtosecond
FemtoLASIK in Xiangyang First Hospital is a kind of laser refractive surgery that is widely used in ophthalmic surgery at present. It uses femtosecond laser technology to correct myopia, hyperopia and astigmatism. Xiangyang No. 1 Hospital, as a professional ophthalmic hospital, provides high level femtosecond laser surgery, and is in the leading position in technology and equipment in China.
Advantages of femtosecond laser surgery
Femtosecond laser surgery has many advantages over traditional laser surgery, which will be described in detail from four aspects below.
1. More accurate operation process
Femtosecond laser surgery uses every femtosecond generated by the laser to cut corneal tissue, which is more accurate than traditional surgery. This accuracy is mainly reflected in the following aspects:
First, the femtosecond laser can precisely control the cutting position and size to achieve the best surgical effect. Secondly, because the cutting speed generated by laser excitation is very fast, the heating time for the cornea during the operation is short, and there is almost no heat conduction to the surrounding tissues, thus avoiding the thermal damage to the cornea during the operation to the greatest extent. Finally, femtosecond laser surgery can make the cut edge of the cornea smoother, and reduce postoperative discomfort and recovery period.
2. Faster recovery time
Traditional laser surgery requires a long time to restore vision after surgery, while femtosecond laser surgery can enable patients to achieve rapid vision restoration in a relatively short time. This is mainly due to the standardized process of cutting and repairing cornea by femtosecond laser surgery, and the faster recovery of vision after surgery.
In addition, the femtosecond laser surgery is less invasive to the corneal tissue, and the incision is small. After the surgery, there is no need for large-scale dressing and nursing, and the patient can quickly return to normal life. This is especially important for patients who are busy with work, and they can return to work as soon as possible.
3. Wide range of indications
Femtosecond laser surgery is applicable to a variety of vision problems, including myopia, hyperopia and astigmatism. And it has a good effect in astigmatism correction. It can be customized according to the specific situation of patients, and different surgical methods can be implemented for different degrees and types of vision problems to achieve the best correction effect.
In addition, femtosecond laser surgery has certain correction ability for some ophthalmic problems related to corneal morphology, such as corneal diseases, irregular corneal curvature, etc. This makes femtosecond laser surgery the first choice for many ophthalmic problems.
4. Long term stability effect
Femtosecond laser surgery can not only correct vision problems, but also bring good long-term results. Compared with other laser surgery methods, femtosecond laser surgery has smaller changes in corneal structure, higher stability of corneal refractive power after surgery, and relatively small changes in patients' vision. Therefore, patients can enjoy stable visual effects for a long time after receiving femtosecond laser surgery, and reduce the possibility of needing correction again.
Summary
As a high-precision and high-efficiency laser surgery method, the femtosecond surgery in Xiangyang No. 1 Hospital has the advantages of more accurate surgical process, faster recovery time, wide range of indications and long-term stable effect. The femtosecond laser surgery can meet the correction needs of different vision problems and improve the quality of life of patients by carrying out tailored surgical methods according to the specific conditions of different patients.
