Lens replacement surgery is a form of refractive surgery aimed at correction of short or long sightedness (myopia, hyperopia and astigmatism). It is also referred to as ‘Refractive lens exchange (RLE)’ or ‘Presbyopic refractive lens exchange (PRELEX)’.
In Lens replacement surgery, the patients own crystalline lens is removed and replaced with a clear high definition multifocal or multifocal toric intraocular lens to correct the pre-existing refractive error to provide maximum spectacle or contact lens independence to the patient. This surgery is often considered for patients who are 50 years of age and have high degrees of refractive error in their spectacles and contact lenses.
Patients who have the lens replacement surgery in their 50’s will not develop cataracts and unlikely to require a further surgical intervention later in their life but have the benefit of spectacle free vision for many years of their life.
A monofocal IOL is a common form of IOL that would allow good sight at distance and patients will need to use specs or varifocal glasses for all reading tasks including computer work and close reading. This is the IOL that is used commonly in all NHS cataract procedures in the UK.
These are advanced optic IOL’s aimed to correct astigmatism, presbyopia, short sight and hyperopia to provide maximum spectacle independence for distance and reading for patients undergoing cataract surgery. The types of premium IOL are Toric IOL, Multifocal IOL and Multifocal toric IOL.
Based on the pre-operative examination and patients own refractive eye status (myopia, hyperopia and astigmatism), Mr Rajan will be able to advice on the suitable premium IOL that would benefit your eye condition. Not all patients are suitable for multifocal IOL’s and it depends on their dry eye status, cornea, retina and macula co-morbidities.
Toric IOL corrects pre-existing corneal astigmatism and have excellent potential to improve quality of the distance vision without the need for spectacles or contact lenses.
Multifocal IOL aims at providing good distance vision following cataract surgery and at the same time allows reading vision without the requirement for spectacles. Multifocal IOL comes in different designs and power to cater for patients preference to see clearly at 30 or 60 cms (reading and computer use) without the need for near vision glasses.
Multifocal toric IOL
Multifocal toric IOL’s have the combined ability to provide good distance acuity and reading function together with the correction of pre-existing astigmatism.
Laser assisted cataract surgery is a latest innovation in the field for eye surgery whereby the surgical steps are performed by the femto laserthat adds precision to the technique. The surgeon is then able to remove the lens through a micro incision and complete the artificial lens insertion.
