What is the difference between full femtosecond surgery and traditional laser surgery in Wuhan Tongji Hospital?
Wuhan Tongji Hospital is a well-known ophthalmic hospital. In recent years, it has introduced advanced ophthalmic surgery techniques, including full femtosecond surgery. Compared with traditional laser surgery, full femtosecond surgery has obvious differences in many aspects. This article will elaborate on both from the perspective of surgical principle, efficacy, postoperative recovery and risk.
Operation principle
The traditional laser surgery mainly uses excimer laser technology, which changes the shape of the cornea by cauterizing or cutting it to correct vision. The full femtosecond surgery uses more advanced excimer laser technology. Its unique feature is that the femtosecond laser is used to achieve corneal ablation, and the micro force cutter used in traditional laser surgery is no longer needed, thus reducing the mechanical damage to the cornea caused by surgery.
The operation principle of full femtosecond surgery is to create an appropriate corneal flap while cutting the cornea through laser, so as to carry out subsequent vision correction surgery. The advantage of this cutting method is that it can achieve more accurate and safer corneal cutting, thus improving the success rate and effect of surgery.
curative effect
Traditional laser surgery is effective in correcting myopia, hyperopia and astigmatism. However, in some special cases, incomplete correction may exist. The full femtosecond surgery is more accurate in correcting various refractive degrees and complex refractive problems, and can achieve more accurate correction results.
In addition, full femtosecond surgery can also improve the shape of the cornea through corneal ablation, so as to treat corneal diseases, such as corneal collapse and hydrocornea. Therefore, the efficacy of full femtosecond surgery is more comprehensive and can meet the needs of more patients.
Postoperative recovery
Postoperative recovery is an important part of surgery and one of the most concerned problems of patients. Compared with traditional laser surgery, full femtosecond surgery has faster postoperative recovery speed.
On the one hand, full femtosecond surgery has less mechanical damage to the cornea during the operation, reducing the pain and edema at the cutting site, so that patients' discomfort after the operation is significantly reduced.
On the other hand, full femtosecond surgery can accurately control corneal thickness and avoid irregular cutting surface when cutting cornea. This makes the recovery of cornea and vision faster after surgery.
risk
In terms of surgical risks, although full femtosecond surgery is more advanced and safe than traditional laser surgery, there are still some potential risks.
First, full femtosecond surgery requires the formation of a flap on the cornea, which increases the risk of corneal flap detachment. This requires strict control of the surgical procedures and techniques to avoid possible complications.
In addition, full femtosecond surgery may cause the intraocular pressure to rise when cutting the cornea, which may lead to the risk of high intraocular pressure during the operation. Therefore, before the full femtosecond surgery, doctors need to closely monitor the patient's intraocular pressure to ensure the safety of the surgery.
summary
From the aspects of operation principle, curative effect, postoperative recovery and risk, the full femtosecond surgery in Wuhan Tongji Hospital has obvious advantages over traditional laser surgery. Full femtosecond surgery achieves a more accurate correction effect through more accurate and safer corneal ablation, with faster postoperative recovery and lower risk. Therefore, for patients who need corneal correction surgery, the full femtosecond surgery in Wuhan Tongji Hospital is a reliable choice.
