What Are the Risks of Lens Replacement Surgery?
ANSWER
Like any surgical procedure, Lens Replacement Surgery carries some risks. Fortunately, serious complications are rare, particularly when the procedure is performed by experienced surgeons and following a comprehensive pre-operative examination.
Patients considering Lens Replacement Surgery abroad (also known as RLE – Refractive Lens Exchange) often ask about potential risks before travelling to Prague for treatment. The good news is that modern Lens Replacement Surgery is based on the same advanced techniques used in cataract surgery, one of the most commonly performed and successful procedures worldwide.
Possible complications may include:
Posterior Capsule Opacification (PCO)
PCO is the most common long-term complication after Lens Replacement Surgery. It occurs when the membrane behind the artificial lens becomes cloudy months or years after surgery. PCO is not dangerous and can usually be corrected with a quick, painless YAG laser treatment that takes only a few minutes. At our clinic, this treatment is offered free of charge within one year of surgery as a complimentary service for our clients.
Cystoid Macular Oedema (CME)
CME is a rare swelling of the central retina (macula). In most cases, it can be successfully treated with anti-inflammatory eye drops and careful monitoring.
Dry Eyes, Glare and Halo Effects
Some patients may notice temporary dry eyes, glare or halo effects around lights, particularly during the first weeks or months after surgery when adapting to premium trifocal lenses.
Halo effects are a normal part of the neuroadaptation process. During this period, the brain gradually learns how to process visual information from the new intraocular lenses and adapt to multiple focal distances. Most patients find that these visual phenomena become less noticeable over time as adaptation progresses.
The majority of patients successfully adapt to their new lenses and enjoy excellent vision at near, intermediate and distance ranges without relying on glasses.
How We Minimise the Risks of Lens Replacement Surgery
One of the most important factors in achieving excellent outcomes is surgeon experience, careful patient selection and comprehensive aftercare.
Our Prague refractive eye surgeons perform a detailed 2–3 hour pre-operative examination before Lens Replacement Surgery. This allows us to assess your eye health, take precise measurements and select the most suitable premium intraocular lens for your individual visual needs.
The procedure itself is performed under local anaesthesia using anaesthetic eye drops and typically takes only 10–15 minutes per eye. Both eyes are usually treated on the same day, making the treatment more convenient for patients travelling abroad to Prague for Lens Replacement Surgery.
Before Refractive Lens exchange surgery, patients receive detailed instructions explaining how to prepare for the procedure. After surgery, every patient receives comprehensive post-operative instructions together with a complimentary set of prescribed eye drops, including antibiotic and anti-inflammatory eye drops. These medications play an important role in reducing the risk of infection, supporting healing and helping to achieve the best possible visual outcome.
Before returning home, all patients attend a post-operative check-up the following day. During this appointment, our medical team performs a series of eye examinations and measurements to monitor healing, assess visual outcomes and check for any signs of complications. The results are reviewed by an eye doctor to ensure recovery is progressing as expected and that it is safe for the patient to travel home, including by air.
Patients are also advised how to care for their eyes during recovery. This includes avoiding rubbing the eyes, swimming pools, hot tubs, saunas, dusty environments and strenuous exercise for several weeks after surgery. Wearing sunglasses outdoors and following all post-operative instructions can help support a smooth recovery.
Based on many years of surgical experience, our surgeons prefer proven microsurgical techniques that provide excellent control throughout the procedure and consistently outstanding results.
For most patients, the benefits of Lens Replacement Surgery far outweigh the risks. The vast majority experience a smooth recovery and a significant improvement in vision, often within just a few days.
Patients from the UK, Ireland, USA, Canada, Australia and New Zealand regularly travel to Prague for Lens Replacement Surgery because of the combination of experienced surgeons, modern technology and comprehensive aftercare.
