Routine intra ocular lenses (IOLs) are placed inside the remains of the lens capsule after removal of the clouded natural lens material. The lens implants hang by their haptics safely inside the ‘bag’ at the very anatomical position of the natural lens.
But in some patients, due to trauma, disease or some congenital conditions, the capsule into which the lens implants are normally deposited is absent or damaged and incapable of securely holding the lens implant. Earlier this used to mean the surgeon had to resort to implanting an anterior chamber IOL which is placed in front of the iris. Not only was this not the normal anatomical position of the lens, there was the added risk of damage to the inside of the cornea.
At PNRF, Dr Manoj Saxena has on numerous such occasions implanted the much more satisfactory but technically more complex, glued IOL. This special lens implant is placed at the position of the natural lens but is fixed securely to the sclera with the use of bio-glue. The final cosmetic and visual effect is just like that of a routine posterior chamber IOL.
