Lens Replacement Surgery FAQs
What is lens replacement surgery?
Lens replacement surgery replaces your eye’s natural lens with an artificial intraocular lens to improve vision and reduce dependence on glasses or contact lenses. At Centre for Sight, it is also referred to as refractive lens exchange and is used to address presbyopia, long-sightedness, short-sightedness and astigmatism.
Who is lens replacement surgery usually suitable for?
This treatment is often considered by people over 50 who want a longer-term vision correction option, especially if reading glasses are becoming more necessary or laser eye surgery may not be the best fit. Centre for Sight uses detailed testing and consultant review to check whether the treatment and lens type are suitable for your eyes and lifestyle.
What happens during the procedure?
After your consultation and diagnostic work-up, the eye is numbed with local anaesthetic and the natural lens is gently removed before the new lens is inserted. The procedure usually takes around 20 to 30 minutes per eye, and Centre for Sight uses laser assistance in all lens replacement cases at no extra cost.
Is lens replacement surgery painful?
Lens replacement surgery is not usually described as painful because the eye is numbed before treatment, although you may notice mild pressure or bright lights during the procedure. Optional sedation may also be available, helping the experience feel calmer and more comfortable.
What lens options are available?
Lens options can include monofocal lenses for one main distance, multifocal lenses for a broader range of vision, toric lenses for astigmatism and extended depth of focus lenses for stronger intermediate and distance vision. Centre for Sight explains the pros, trade-offs and likely visual outcome of each option before treatment is planned.
Will I still need glasses afterwards?
Some patients reduce their need for glasses significantly, but the answer depends on the health of your eyes, your prescription and the type of lens chosen. Centre for Sight aims to give clear, realistic advice before surgery so you understand what level of spectacle independence may be achievable for you.
What is recovery like after lens replacement surgery?
Many people notice sharper vision within hours or days, although it can take a little longer for the eyes to settle fully and adapt to a new lens. Centre for Sight provides structured aftercare, guidance on eye drops and post-operative checks for 90 days after treatment.
Are there any risks or side effects to know about?
As with any eye procedure, there are risks, but serious complications are uncommon when treatment is carefully assessed and planned. Some patients notice temporary halos, glare or an adjustment period after surgery, and Centre for Sight discusses these points in advance so you can make an informed decision.
How much does lens replacement surgery cost?
Centre for Sight provides transparent pricing, with consultations from £445 and lens replacement packages priced according to the lens selected, such as monofocal, toric or multifocal options. Finance is also available, including up to 24 months interest-free credit subject to status, which can make treatment costs easier to spread.
