Lens Exchange Surgery
Clear lens extraction (CLE) or refractive lens exchange surgery is a type of surgery performed to treat patients with reading vision difficulty. The surgery is exactly the same as cataract surgery in terms of technique, but is performed before the formation of cataract (hence Clear Lens), when the lens begins to stiffen with age and becomes presbyopic. You may have heard this called the Clarivu procedure by Optegra. The technologies and techniques of cataract surgery are safe, sophisticated, and well established, as tens of millions of patients have had cataract surgery around the world. The purpose of lens exchange in a presbyopic patient is that it allows a multifocal intraocular lens to be placed within the eye. This allows the patient to be largely independent of spectacles for near and distance vision. The majority of patients having multifocals find that they don't need glasses for 90-95 % of daily activities.
An added advantage of lens exchange surgery is that you won't develop a cataract later in life. Speak to your surgeon about whether lens exchange is an option for you. Mr Angunawela performs lens exchange surgery with the femtosecond laser for added safety and technical precision.
