Artificial lens dislocation after cataract surgery, how to prevent it?

Cataracts are eye diseases in which the lens is cloudy and the vision is blurred or blurred. It can also appear as a complication of ophthalmic or systemic diseases such as trauma, uveitis, and diabetes, but the most common cause is aging. The fundamental treatment for cataracts is to replace the surgically turbid lens with an artificial lens, which is rare after surgery, but caution is needed as artificial lens dislocation can occur, which can cause the lens to fall out of place.
Cataract surgery is performed by removing the lens from which the turbidity has occurred and inserting an artificial lens. In the early stages of cataracts, vision loss progresses gradually, so people miss the treatment period by mistaking it for presbyopia. If left unattended, the treatment process becomes difficult and surgery is required when it progresses to a certain extent, so it is important to detect it early, slow down the progress, and perform treatment suitable for the patient's condition.
Artificial lens dislocation is usually caused by weakening or damage to the support of the lens pouch that encloses the lens. ▲Older patients who have been long after cataract surgery ▲High myopia ▲Have retinal surgery ▲Have closed-angle glaucoma ▲If the eye or head is traumatized, the coupling structure supporting the lens pouch may weaken and the possibility of artificial lens dislocation may be relatively higher.
In addition, if you have a habit of rubbing your eyes, there is a possibility that the artificial lens will be pushed to one side or dislocated due to continuous damage to the ciliary body (a bundle of fibers connecting the lens and the ciliary body) that supports the artificial lens.
If the artificial lens dislocation progresses, the symptoms may vary depending on the degree, but if it is partially out of place, things may appear overlapping, blurry in front, or light spreading. If you are completely out of place, rapid vision loss can occur.
If stomach symptoms appear after cataract surgery, it is recommended to visit an ophthalmologist to check whether the prosthetic lens is in place because there is a possibility that a dislocation of the prosthetic lens may have occurred.
Treatment is performed through surgery, and the method is determined according to the degree of damage to the lens pouch and ciliary body. Position correction is a method of correcting the existing position of the artificial lens, and scleral fixation is a method of removing the artificial lens inserted in the past, inserting a new artificial lens, and tying it to the sclera (inside the eye whites) through sutures and fixing it. In particular, if the artificial lens is completely separated and is in the vitreous cavity, it can cause permanent damage to the retina, so it is necessary to remove it as soon as possible through vitreous resection.
In order to prevent dislocation of the artificial lens after undergoing cataract surgery, it is recommended to be careful of strong impact on the eyes or frequent rubbing of the eyes. In addition, even if there are no special symptoms, it is recommended to check that the artificial lens is well positioned in place and the damage has not progressed through regular checkups.
Lee Ji-hyun, a specialist at Kim Ophthalmology Hospital Retinal Hospital, said "Artificial lens dislocation surgery can cause more pain and a relatively longer period of surgery and recovery than normal cataract surgery."It is important to check the progress through regular checkups even after cataract surgery, and if the artificial lens is dislocated, it is necessary to undergo surgery by an experienced specialist."
