What is LASIK?


LASIK is a surgical procedure used to treat vision problems. It changes the shape of the cornea. Patients who wear contact lenses must stop wearing them for at least a week before their surgery. However, this time period may vary depending on the contact lens wearer. Most patients experience minimal discomfort and recovery time is around 10 minutes. During surgery, patients lie on their backs in a reclining chair. Before the procedure, numbing drops are placed into the eye. An instrument is then used to gently hold the eyelids open.


LASIK is a refractive surgery that corrects various vision problems, including myopia, hyperopia, and astigmatism. This procedure works by making tiny adjustments to the cornea, allowing for improved vision. It is also known as laser eye surgery or laser vision correction. During this procedure, the surgeon uses a laser to make tiny changes to the cornea.

Before undergoing LASIK, a patient must undergo a thorough examination and medical history. This is important to identify potential complications of the surgery. During preoperative screening, a doctor will determine the degree of the patient’s refractive error. This condition affects how distant objects appear in the eyes, and can result in blurred vision. By correcting this condition, LASIK can make distant objects appear clearly and close up. ICL 렌즈삽입술

During the recovery period, patients should avoid strenuous physical activities. The eye may take anywhere from three to six months to heal completely. Some patients experience temporary vision fluctuations, but these usually subside in time. For the first few months after the procedure, patients can return to work, although doctors may advise waiting at least a day. It is also important to avoid swimming and strenuous exercise for a few weeks. Patients should also follow the doctor’s instructions for applying eye drops.

Although the FDA has approved LASIK, it is not right for everyone. Some people are not suitable candidates for the surgery, or the results may be less than optimal. For this reason, it is vital to have a thorough pre-operative evaluation. The doctor will be able to evaluate your eye condition and make any necessary adjustments to ensure the best outcome.

This procedure usually takes less than 20 minutes for each eye. There will be a short period of monitoring after the procedure. Afterward, patients are free to return to their normal activities. The recovery period can vary from one person to the next. It depends on how quickly the patient heals. In general, the recovery time ranges from a few weeks to a few months.

Prior to the surgery, patients should remove their contact lenses for at least two weeks. In addition, patients should arrange for someone to drive them home. This is important because they will not be able to drive after the procedure. Furthermore, patients should avoid wearing makeup and perfume. It is also crucial to avoid bulky hair accessories.

While both PRK and LASIK can improve your vision, not everyone is a candidate for either procedure. Some reasons for not being a candidate include corneal thickness or surface problems. Other patients are not candidates due to past trauma, prior eye surgery, or lifestyle. The doctor may recommend PRK in these patients instead.

LASIK uses a laser to reshape the cornea, which enables light to focus more clearly on the retina. This surgery is highly effective, as it corrects refractive errors in the eye. To perform the procedure, the surgeon makes a small flap in the upper cornea and lifts it upward. The laser then removes microscopic amounts of tissue to alter the cornea. After the procedure, the cornea is permanently reshaped. This procedure eliminates the need for glasses or contacts.

The procedure usually lasts less than 30 minutes, and you should be done with it the next day. During the procedure, you may experience some discomfort, but it should be minimal. You may feel pressure or a mild itching sensation. You may also feel a light pressure on the eye afterward. 망막전문의

During the surgery, you will be administered local anesthetic and medication to ease discomfort. You will also be provided with a lid speculum to keep your eyelids open during the procedure. During the procedure, the surgeon will mark the cornea with an ink marker. The doctor will then use an excimer laser to remove the tissue. This reshapes the cornea to allow light to enter.

After LASIK, your vision may not be perfect, but it will improve. It will also reduce your dependence on contact lenses and glasses. Although you may experience some problems in the days following your surgery, your doctor should give you regular eye drops to ease the dryness. Another common side effect is increased light sensitivity. You may even experience double vision. If you have trouble driving at night, you may need to consult an optometrist for further information about the surgery.
