In this fatwa:
Resorting to a laser eye surgery would be allowed provided that there is a genuine need and that the surgery is safe from potential harms.
In his answer to your question, Mufti Muhammad Ibn Adam Al-Kawthari, Director and researcher at the Institute of Islamic Jurisprudence (Darul Iftaa, www.daruliftaa.com), Member of the Al-Qalam Shari`ah Scholars Panel, and advisor on Islamic Banking, states:
Eye surgeries are becoming more and more common with progress made in the medical field. Refractive eye surgery is any eye surgery used to improve the refractive state of the eye and decrease dependency on glasses or contact lenses. The most common methods today use lasers to reshape the cornea.
The Islamic ruling with regard to all types of surgeries is that it will be allowed to resort to them as long as there is a genuine medical need.
Imam Abu Dawud, Imam An-Nasa’i and Imam At-Tirmidhi (Allah have mercy on them) have recorded in their respective Sunan collections, that a Companion by the name of `Arfajah ibn As`ad (Allah be pleased with him) had his nose damaged in the battle of the Kulab. He replaced it first with silver and then with a nose made of gold, with the order and consent of the Messenger of Allah (peace be upon him).
It is stated in Al-Fatawa Al-Hindiyyah, a major Hanafi Fiqh reference:
“If one intends to cut off an extra finger, it will be permissible as long as there is no fear of perishing.” (4/114)
However, surgery for beatification purposes and when there is no need will remain unlawful (haram), for it involves mutilation (muthla), tampering with one’s body and changing the nature created by Allah Most High.
In light of this, resorting to a laser eye surgery would be allowed provided the following two conditions are met:
1- There is a genuine need. If one is able to put up with wearing eyeglasses or contact lenses, then one should avoid having laser treatment being done. However, not everyone is comfortable with wearing glasses, especially when one has to wear them all the time.
Those who like to read before retiring to bed sometimes fall asleep with their glasses on, which can be dangerous at times.
Contact lenses are too complicated for some to wear. Some people are not satisfied with vision correction by either eyeglasses or contact lenses.
Thus, although eyeglasses and contact lenses are suitable and ideal alternatives, one may resort to eye surgery if one still feels the need.
2- The surgery is safe from potential harms. One must enquire from specialists whether it would be safe for one to undergo such surgery.
Almighty Allah knows best.
