Presbyopia causes reading to become blurred.
Presbyopia is an age-related eye condition that causes difficulty in reading without glasses and affects people in their middle-ages.
LENS IMPLANT SURGERY
Patients with cataract need not wait for many years for their cataract to mature and harden before undergoing surgery. With the modern advances in ophthalmic skills and technology, soft cataracts are easily removed and patients undergoing a cataract procedure have a once in a lifetime chance to change their imperfect eye errors (eg. myopia, presbyopia and astigmatism) into the perfect eye that they deserve without any refractive errors at all, achieving total spectacle freedom.
At Novena Bladeless Cataract Surgery & Eye Specialist Centre, only scientifically proven and time tested technologies are used in correcting presbyopia. Patients are first assessed for cataracts. If diagnosed with cataract, our patients will have a choice between Multi-focal or Mono-focal lens implants, either of which when implanted during cataract surgery, is able to remove all refractive errors (eg. myopia, presbyopia and astigmatism) to achieve total spectacle freedom. This procedure is highly successful, takes 15 minutes and is carried out under local anaesthesia.
Multi-focal lens technology:
Multi-focal lens implants are specially engineered to provide both a distance focus and a near focus at all times. Multi-focal lens implants are similar to wearing “progressive” spectacles which allow distance, intermediate and near focus. Instead of wearing glasses on the face, multi-focal lens implants are implanted inside the eye, so that post-operative glasses are not necessary. The brain will neuro-adapt to the multi-focal visual system post-operatively, such that it will automatically select for the eye to focus at any required distance.
Mono-focal lens technology:
If a mono-focal lens implants is desired, total spectacle freedom is achieved by creating mono-vision. Mono-vision can be achieved during a cataract surgery by implanting a mono-focal lens in one eye that is set for near-vision, while implanting another mono-focal lens in the other eye that is set to see far. This process of neuro-adaptation by the brain to mono-vision usually takes 1 to 2 weeks, after which the brain begins to use the eyes naturally in a mono-vision manner and a person becomes unaware which eye is focused at near and which is focused at distance.
Novena Bladeless Cataract Surgery & Eye Specialist Centre uses aspheric HD (high-definition) mono-focal lenses, like our HD TV screens, offering the sharpest image amongst any available implants. These lenses provide excellent contrast-sensitivity and extremely high quality of vision in a variety of lighting conditions. Individuals who require excellent distance vision or those who frequently drive at night, may be well suited with an HD mono-focal lens implant. For people with eye diseases such as macular degeneration or glaucoma, the compromised state of the retina may often be assisted by the HD mono-focal lens implant to form the sharpest image possible on the retina.
Patients electing to have lens implantation surgery to reduce their need for glasses will never have to worry about cataracts later on in life. Once removed, a cataract will never return. The eye prescription carried in the new lens implant is stable for the rest of your life.
Younger patients with presbyopia but no cataracts should opt for LASIK. LASIK is a type of eye surgery that uses a laser from the LASIK machine to change the shape of the cornea, thereby treating all refractive errors at once.
A currently available FDA-approved procedure that corrects presbyopia is the mono-vision LASIK, where one eye is corrected for distance-vision and the other eye is corrected for near-vision. In a simple 10 minutes procedure under topical anaesthesia, all myopia, presbyopia and astigmatism are treated by the LASIK laser. During your eye assessment at our eye specialist centre, you will get the opportunity to experience mono-vision with trial lenses before committing for the mono-vision LASIK. Another option will be Implantable Contact Lens, though not FDA-approved for patients above the age of 45.
