Refractive lens exchange

Brar Eye Centre, Eye Hospital: Refractive lens exchange is also known as clear lens extraction or lens replacement surgery and it is a better option for people with farsightedness and presbyopia. With the refractive lens exchange (RLE) the naturally clear lens is replaced with the artificial IOL (Intraocular lens) and refractive error is corrected and patient focus is better.

Lens replacement surgery

The lens replacement surgery does not need FDA approval and some eye surgeons will perform the surgery off label in certain cases. This is considered a legal option sometimes and the most effective choice to deal with vision issues.

How refractive lens exchange is helpful?

RLE is beneficial for people with extreme farsightedness or presbyopia. It is for those you cannot get LASIK, PRK, or phakic IOL surgery.

How lens replacement surgery is beneficial?

Lens replacement surgery can correct nearsightedness but this option is not suitable when the patient can undergo PRK, LASIK, or phakic IOLs.

The cataract surgery in Ludhiana and the refractive lens is virtually the same as a refractive lens exchange.

With cataract surgery, the artificial lenses are of 3 types and the need depends on what is the vision issue and eye health.

What is the procedure of refractive lens exchange?

The lens replacement surgery takes around 15 minutes and this procedure is an outpatient method. To correct each eye the procedure is done separately, and it is performed one week apart.

During RLE, the numbing anesthetic drops are used which helps the patient to be at comfort. The best part is that the patient will have immediate vision improvement.

To see the final results from the treatment it can take around several weeks, and you might notice vision disturbances such as blurry vision halos and glare. Keep in mind if you feel any sensation then it is part of the process of eye healing.

One week following the surgery, you can drive on your own and get back to your normal working routine. Just make sure to follow the surgeon’s instructions during the recovery period.

You won’t be able to feel you have an artificial lens in your eyes. Also, others will not be able to tell you to have it inside the eyes. The IOL is the permanent replacement for the natural lens so that you can see things clearly for the rest of your life. With time, there is minimal risk of regression.

Vision after refractive lens exchange

The type of IOL is used to determine whether you need contact lenses or eyeglasses. Mostly, the lens exchange and cataract surgery use the monofocal IOLs. With these lenses, the vision is best, and the chances of vision disturbances are reduced.
