Refractive Lens Exchange (RLE) is a procedure that replaces a dysfunctional natural lens (without cataracts) with an artificial lens to correct vision. RLE Surgery aims to improve vision by replacing the natural lens with an artificial lens, allowing for clearer and sharper vision. RLE Surgery is recommended for individuals around 40 years or older with stable vision for at least six months and no history of eye diseases. It is an option when laser vision correction treatments like LASIK are not suitable.
Cataract/RLE surgery may be suitable for you if you have blurry vision or wish to reduce reliance on glasses or contact lenses. However, it is not recommended if you have a detached retina, advanced macular degeneration, or are younger than 21 years old.
RLE (Refractive Lens Exchange) and cataract surgery are similar in that they both involve removing the natural lens of the eye and replacing it with an artificial lens. However, the main difference is the purpose of the surgery. RLE is an elective procedure done to reduce the need for glasses or contact lenses, while cataract surgery is performed to improve vision when cataracts are causing problems with daily activities.
You won't feel any pain or discomfort because the surgery is done under anaesthesia. After the surgery, it is normal to experience mild eye irritation for a few hours, but your doctor can prescribe Panadol or ibuprofen to help manage any discomfort you may have for a day or two following the procedure.
Most side effects of cataract eye surgery disappear within a day or two, but it may take about 4-6 weeks for your vision to fully recover.
For many reasons, your surgeon is most likely to recommend intraocular surgery one eye at a time. On occasions, same-day surgery to both eyes is performed. It is important to consult with your cataract surgeon to determine if this option is suitable for your specific situation.
You may experience some side effects, after the surgery such as increased sensitivity to light, difficulty seeing at night, and trouble with driving or seeing well in low-light conditions. You might also notice rings or halos around lights and experience glare at night. These effects are usually temporary and improve over time.
The surgery itself for both Cataracts and RLE takes around 30 minutes. You should plan for a total time commitment of about 2-3 hours, including the pre-operative preparation and post-operative recovery period.
There are two types of lenses used for eye surgery:
Monofocal lenses: These lenses help you see either up close or far away, but not both at the same time. You may still need glasses for some activities.
Multifocal lenses: These lenses allow you to see both near and far distances without glasses. They can also correct astigmatism, giving you a wider range of clear vision, with less reliance on glasses afterwards.
It is advisable to take the rest of the day off and avoid strenuous activities after undergoing cataract or RLE surgery. It is recommended to have at least 48 hours of downtime before returning to your day-to-day functions. It is important to make sure to arrange for someone to drive you home after the surgery. You will need to discuss with your specialist how long to take off work and driving after the procedure, however, it is usual to expect to take 1 week off these activities after each procedure.
