Vision correction for people under 45 with Large spectacle prescription
For people who have a larger than normal spectacle or contact lens prescription but are still under the age of forty five we have a range of specialised lens implants that can be used without removal of the natural lens. At Bettersight we feel that unless you have an extremely large spectacle prescription we would prefer not to remove the natural lens whilst it continues to provide you with a reasonable degree of near range vision (called accommodation). For most people this accommodation starts showing clear signs of declining after the age of forty five and especially so after the age of fifty.
The lens implants that can help correct poor eyesight for people who fall into this category are sometimes referred to as ‘contact lens implants’ and also ‘implantable contact lenses’. The medical term for such lens implants is ‘phakic’ lens implants.
Why consider a Phakic Implantable lens implant (ICL)?
- ICL treatments are considered by most experts to provide higher quality vision than Laser correction when correcting large prescriptions.
- ICL effect is permanent whilst the implant is in place.
- ICL’s can be removed and thus there effect can be reversible too.
- ICL’s will allow natural, age related, near focusing as your natural lens is still in place. Obviously this will fade with age too !
Phakic lens implants come in a variety of types – but essentially can be divided into three main types of lens implant. Here we outline the three major variety of phakic lens implant.
Types of Phakic Lens Implant
- Iris Clip Anterior Chamber Lens Implants
These implants are produced in both a silicone polymer material for insertion through a micro-incision and also in PMMA material which are for larger prescriptions and normally require a medium sized incision.
Iris clip lens implants have been avialable for many years and can be used to reduce or eliminate high degrees of myopia (short sight), hyperopia (long sight) as well as astigmatism. Surgery normally takes around twenty minutes for each eye with only one eye being treated at a time. Most patients are able to undergo this treatment with local anaesthetic. Vision recovery is often very rapid.
- Angle fixated Anterior Chamber Lens Implants
The Cachet IOL is fashioned from the celebrated acrysof material that has been used in implant manufacture for many years. The Cachet lens implant is designed to be inserted into the eye via a tiny injection cartridge. It is not clipped to the iris but rather its footplates allow miniscule contact to the space between the cornea and the iris – called the angle. We can correct upto -16 dioptres of myopia (short sight) with this lens. At the time of writing this implant cannot be used to correct hyperopia (long sight)
- Posterior Chamber Phakic ICL
In this variety of lenses – the implant is designed to be placed in the space between the iris and the natural lens – this space is called the ciliary sulcus. Implants positioned here are virtually invisible when compared to other types of ICL. However their closer proximity to the natural lens does mean a higher risk of developing cataract and some forms of glaucoma too hence this type of implant has generally been less popular both with surgeons and with patients.
Bettersights View of ICL Treatments
At Bettersight we have witnessed the amazing transformations in the quality of life reported to us by many patients who underwent ICL treatment under our care. Many of these patients had been told by other providers that their prescriptions were too severe for any treatment.
