A lensectomy is a microsurgery procedure that removes part or all of the crystalline lens from the eye. The lensectomy procedure is performed to treat a wide range of vitreoretinal disorders, including:
- Retained lens fragments after cataract surgery
- A dislocated intraocular lens (IOL) following cataract surgery
- Complex retinal detachments
- Intraocular foreign body
A lensectomy is usually performed as an ambulatory procedure, meaning that patients return home the same day as long as no complications have been experienced.
The Lensectomy Procedure
The lensectomy procedure begins with the surgeon creating a tiny incision in the wall of the eye. If the goal of this procedure is to remove the entire lens, a phacoemulsification technique can be utilized to break up the lens with vibrations or sound waves. Using a miniature suction instrument the surgeon will remove the lens and any remaining fragments. A saline solution is then injected into the eye to restore intraocular pressure. If a lensectomy is being performed to remove a cataract, incisions may instead be made towards the front of the eye. This procedure takes about 1 to 2 hours to perform, depending on the patient's individual condition.
There are certain risks associated with any type of surgery, including a lensectomy. These risks may include:
- Retinal tear
- Retinal detachment
