Cataract Surgery FAQs
Blue Fin Vision® consultants answer the most common questions about private cataract surgery. From suitability to recovery, risks to costs, find reassurance and practical guidance to help you make an informed decision about restoring your vision.
What is cataract surgery?
Cataract surgery removes the cloudy natural lens from your eye and replaces it with a clear artificial intraocular lens (IOL). It is one of the most commonly performed and successful surgical procedures worldwide. The operation restores clear vision by eliminating the cloudiness caused by the cataract, allowing light to pass through to the retina properly.
Am I a candidate for cataract surgery?
Cataract surgery is suitable for most adults whose vision is affected by cataracts. You may be a candidate if your cataracts are causing blurred vision, difficulty driving, trouble reading or problems with glare and halos around lights. Your consultant performs a comprehensive eye examination to assess the severity of your cataracts and determine the most appropriate treatment plan and lens choice for your needs.
How long are NHS waiting times for cataract surgery?
NHS waiting times vary significantly depending on location and hospital capacity. The NHS target is 18 weeks from referral to treatment, but many patients experience waits of 3 to 12 months, with some areas reporting waits of over a year. Private cataract surgery typically offers appointments within a few weeks of enquiry.
Is cataract surgery painful?
Cataract surgery is not painful. The procedure is performed under local anaesthetic using numbing eye drops, sometimes with a mild sedative to help you relax. You may feel slight pressure during the operation, but the treatment itself is comfortable. Any post-operative discomfort is typically mild and short-lived.
How long does cataract surgery take?
The procedure usually takes between 5 and 10 minutes per eye. You will be monitored for a short period afterwards before being discharged the same day. The entire visit, including preparation and recovery time, typically lasts a few hours.
What lens options are available for cataract surgery?
Several intraocular lens options are available for cataract surgery depending on your visual requirements – including premium lenses not available on the NHS. Monofocal lenses provide clear vision at one distance and are the standard NHS option. Toric lenses correct astigmatism as well as distance vision. Multifocal and trifocal lenses offer vision at multiple distances, reducing dependence on glasses. Extended depth of focus (EDOF) lenses provide a smooth range of vision with fewer issues from glare and haloes. Your consultant will recommend the most suitable lens based on your lifestyle and visual goals.
What are the risks associated with cataract surgery?
Cataract surgery has an excellent safety record, with serious complications being rare. The most significant risk is infection (endophthalmitis), which occurs in approximately 1 in 1,000 cases. Other potential complications include posterior capsule rupture, retinal detachment, and raised eye pressure. Posterior capsule opacification (PCO), where the lens capsule becomes cloudy, affects roughly 1 in 5 patients over several years but is easily treated with a quick laser procedure.
Will I still need glasses after cataract surgery?
Your need for glasses depends on the lens type chosen. Monofocal lenses correct distance vision, so reading glasses are usually required for close work. Multifocal and trifocal lenses significantly reduce dependence on glasses for most daily activities. Approximately 30% of patients still need some form of glasses after surgery regardless of lens type. Your consultant discusses realistic expectations during your consultation.
How soon will I see improvement after surgery?
Vision often begins to improve within a few days of surgery, though it may be slightly blurry initially. Most patients notice significant improvement within the first week. Full visual recovery typically occurs within 4 to 6 weeks as your eye heals and adjusts to the new lens.
What if my vision does not reach the target prescription?
In some cases, final vision may differ slightly from the target due to individual healing responses. If significant residual refractive error remains, enhancement options are available. These may include laser eye surgery to fine-tune the outcome or, rarely, exchanging the intraocular lens for a different power. Your consultant monitors your progress at follow-up appointments and discusses the most appropriate solution if further correction is needed.
