During RLE, the natural lens of the eye is removed and replaced with an artificial lens implanted during a surgery which is very similar to cataract surgery. The artificial lens implant is designed to allow multiple focusses of your vision so that one can see both in the distance, intermediate and reading or close distances with minimal or no glasses.
The difference between RLE and cataract surgery is that this is performed before cataract develops , with the sole aim of reducing the person’s need for glasses.

When we talk about vision, we can divide into the following:
• 距离远景 – approximately 4 metres away and mainly for driving
• 中间视力 – examples include using a computer screen, reading using gadgets such as iPad or kindle, looking at a menu, gardening or cooking
• 近视 – reading newspapers or book, usually around 40cm away
We can optimise refractive outcomes in accordance to your needs for vision through several artificial or intraocular lenses implanted during the surgery.
Multifocal/ Trifocal lenses: These lenses correct for distance, intermediate and near vision- negating the need for glasses. If glasses are needed, it is often a very weak prescription. The main drawback or cons for these lenses is that it may induce glare or halos. This is worse in dim light conditions and is exaggerated for some individuals especially those with ocular surface or ocular problems.
Extended Depth of Focus (EDOF)lenses: These lenses correct for distance and intermediate vision but reading glasses are likely required for close or reading work.
This is an increasingly popular option for patients with modern gadgets such as the iPad. Most of our daily living now involves mainly intermediate distances. Thus, having distance and intermediate vision may cover the vast majority of needs for many patients, particularly those with mild underlying ocular disease. This lens induced minimal glare as compared to the latter.
RLE is meticulously planned and customised to address the unique visual needs and ocular characteristics of the patient. By integrating advanced diagnostic imaging, intraoperative guidance systems, and patient-specific data, surgeons can tailor the surgical approach, lens selection, and incision placement to optimise visual outcomes and patient satisfaction.

RLE or lens replacement surgery is one of the safest as well as commonest surgeries done world wide. In Europe, approximately 3 million cases are done on a yearly basis. However, as with every procedure and surgery, there will be risks involved. Whilst complications are uncommon , it is important that you consider the risks and benefits as well as impact on you that would be discussed during your initial consultation.
RLE carries similar risks to cataract surgery which has gone through technological advancements in the last decades. Phacoemulsification technique is performed in the majority of the cases.
However, as with every medical procedure and surgeries, there are risks involved.
严重并发症的发生概率约为2%（1/50)
可能包括：
Blurred vision
Some loss of vision
视网膜脱离 – where the the thin layer at the back of your eye (retina) becomes loose
多数严重并发症可通过药物或手术处理。
约0.1%（1/1000）的患者可能因手术直接导致治疗眼永久性视力丧失。
Ms Heng will individualise your risk profile and define the possible complications and outcomes as well as risk vs benefit profile for the individual patients.
Immediately following the RLE surgery, you may experience some improvements in your vision which will improve over time. Full recovery from RLE usually takes a few weeks to a couple of months. Most patients however resume normal activities within a week or two.
Not to worry if your vision fluctuates in the first couple of weeks, you may also experience blurriness, glare, or halos around lights. These effects are expected and gradually subside as your eyes heal with time.
Refractive Lens Exchange (RLE) also known as lens replacement surgery or clear lens exchange is a surgical procedure that involves replacing the natural lens with an artificial one and if aimed to correct refractive errors such as nearsightedness, farsightedness, and astigmatism. Refractive eye surgery such as LASIK and PRK,reshapes the cornea to correct vision.
RLE can be considered for patients who are poor candidates for LASIK due to high refractive errors, thin corneas, or age-related changes in the eye.
It is also a popular solution for individuals over the age of 45 experiencing presbyopia (difficulty in seeing close or reading distance). RLE is able to address both refractive errors and presbyopia simultaneously.
