Subluxated lens

Lens, a key component of vision, rarely dislocates but when it does, vision gets badly messed up. Dislocated lens has to be removed by equally rare microsurgery and supplanted with artificial one.

In Aakash Healthcare, one such unusual case presented itself which was flawlessly repaired by Dr. Prashaant Chaudhry, HOD, and Ophthalmology. Dr. Chaudhry replaced the dislocated one and supplanted an artificial lens. Dislocated lens is scientifically called subluxated lens.Subluxated Lens removal is a rare Surgery. A subluxated lens is one which is displaced from the normal central position in the eye. It can be either above the axis of vision or below the axis of vision

Dr Chaudhry says, “It is unusual but when this happens, the lens can no longer focus light onto the retina and vision is grossly disturbed. This lens needs to be removed by microsurgery.”
Dislocation of a lens is quite rare. While the cause of this is not clearly known, half the cases are caused by injury to the eye. The other half is largely hereditary and affects both eyes. These progressively get dislocated as age advances.

According to Dr. Chaudhry, “when the lens gets displaced from its normal position, vision is affected. Displacement of the lens also causes inflammation in the eye which can cause increase in the eye pressure also known as glaucoma.”

He said further, To replace this normal lens, we have to implant in artificial intraocular lens. However, this cannot be done in a normal way because the lens is removed in its entirety without leaving a support which is normally used to implant the intraocular lens. In the absence of this support, the intraocular lens has to be fixed to the eye with the help of sutures or directly stabilized to the white part of the eye using a technique called glued IOL

In both of these techniques, the patient will need to use different power glasses when looking at a faraway object and when reading. The only way in which the patient can see both far away and read with minimal need for glasses is the use of a special lens called a multifocalliol. For Shivam, the aforesaid patient, we implanted a multifocal IOL with the help of the glued IOL technique.

According to him, his procedure is exceedingly rare and has been reported only once in literature. This disease tends to affect men and women equally and can present from as early as birth too late middle age. It can be easily diagnosed by dilating the pupil of the eye. Normally the edge of the lens cannot be visualized but in dislocated lenses we can see this edge.
