Are you tired of relying constantly on glasses or contact lenses to see clearly? If so, maybe you should consider lasik surgery to improve the focus of your vision. Lasik surgery is one type of refractive surgery, which is a surgical procedure that aims to change the shape of the cornea of the eye to improve vision.
To do this, a laser that has been programmed to erode corneal tissue is needed. With this tool, the surgeon can adjust the curvature of the cornea or make it steeper as needed.
Lasik or laser-assisted in-situ keratomileusis surgery is a medical procedure aimed at treating a number of vision problems, such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. With lasik surgery, you can reduce the use of glasses and contact lenses or even free of both.
But before undergoing a lasik procedure, you need to do an examination and consult with an ophthalmologist first to ensure that you are a good candidate for lasik surgery.
What’s the Lasik Surgery Procedure Like?
Before the lasik surgery procedure begins, you may be given medication to help you relax. After that, the surgeon will give eye drops to make your eyes feel numb when the procedure is done. An eyelid support is then placed to keep the eyes open and prevent blinking.
Aside from the support, the surgeon will also place a suction ring on the eye to prevent the eye from moving. After that, the surgeon starts making small incisions on the surface of the eyeball using a small scalpel or laser. This incision will then form a fold in the cornea. This surgery aims to change the shape of the cornea to be repaired as needed.
Once done, the cornea will be closed again and in a matter of minutes, the crease will stick by itself without the need for stitches. Finally, eye drops are given to help cure.
Usually lasik surgery takes about half an hour. If you need lasik surgery on both eyes, the doctor will do it the same day. You may be scheduled to return to the hospital one to two days after the operation and six months later, depending on the results of the examination. The doctor will monitor the healing process of the eye and evaluate if there are complications.
Usually the eyesight has begun to improve and clearer after two to three months postoperatively. However, the healing time of each person is different. Some are faster, but some are longer.
Just like a general medical procedure, lasik surgery also has a number of risks, such as:
- Dry eye. This operation can temporarily reduce tear production, usually for six months after lasik surgery.
- Trouble with corneal folds. Complications such as infection or healing of imperfect corneal tissue can occur after surgery to make corneal folds.
- Astigmatism. This can occur when tissue erosion is uneven. You may need glasses, contact lenses, or additional surgery to overcome them.
- Light sensitive. You may feel glare or see halos when you are around lights or light sources.
- Vision loss. Although rare, the possibility of this can occur due to postoperative complications. The risk of return of vision problems, such as nearsightedness can also occur after lasik surgery.
- Undercorrections. This condition occurs when the laser erodes too little tissue in the eye.
- Overcorrections. This condition occurs when the laser erodes too much tissue in the eye.
The risk tends to increase in people who have dry eyes, autoimmune diseases, eye disorders (glaucoma, cataracts, herpes simplex, or eye injury), diabetes, and unstable vision caused by pregnancy, hormonal changes, age, and drug use medicine.
People who have nearsightedness with a low severity tend to get better lasik surgery results than those who have nearsightedness with a higher severity. Likewise, people with nearsightedness and astigmatism, whose severity is high, will have a lower success rate of lasik surgery.
To avoid unwanted things, you should avoid the lasik surgery method if you:
- Have good eyesight.
- Likes to do physical activities related to the impact to the face.
- Having large pupils or thin corneas.
- Have a job that might be affected if you have lasik surgery.
- Having vision problems related to aging, such as presbyopia.
For lasik surgery to run smoothly, you must prepare yourself by stopping wearing contact lenses for several weeks before surgery, avoiding wearing eye makeup since the day before the operation, and keeping your eye area clean.
