Experts have recently announced that patients can undergo Lasik treatment after their cataract surgery. In an article in The Straits Times, an elderly gentleman asked whether he could undergo Lasik surgery since his cataract surgery did not correct his astigmatism.
Experts explained that Lasik can be done after cataract surgery if a patient still has a refractive error. It is important, however, that patients are thoroughly assessed to ascertain if they are suitable for Lasik surgery. Before we go into further details, however, let us explain some of the terms used.
Cataract and Its Treatment
A cataract is a condition that affects the lens of the eye. It is exhibited by clouding of the lens that makes vision blurry. It is common among the elderly but can but can be congenital, and can be caused by other medical conditions or injury to the eye.
Singaporean eye clinic Lee Hung Ming Eye Centre explains that cataract surgery involves only 2 steps and takes around 15 – 20 minutes. The cloudy lens is first removed with ultrasound, and an artificial lens is then inserted. The centre adds that it is one of the safest surgical procedures. Patients can go back to their daily activities the following day.
Lasik treatment, on the other hand, is done to treat nearsightedness, farsightedness and astigmatism. Lasik actually stands for Laser-Assisted In Situ Keratomileusis but is widely referred to in its abbreviated form. By use of an excimer laser, tissue is removed from the centre of the cornea or the transparent layer of the eye. This is done to reshape the cornea’s centre, correcting the refractive error in the patient’s eye.
Going back to the feasibility of undergoing Lasik after cataract surgery, patients can have Lasik if their cornea is found suitable for the procedure. Patients who cannot undergo Lasik are those with a thin cornea, glaucoma, retinal detachment and other eye conditions.
Patients must go to eye centres to determine if they are suitable candidates for eye treatment procedures. As seen from the article in the Straits Times, asking a question can go a long way.
