Each eye has a natural lens. In order for us to see clearly the lens has to be clear, and has to have the appropriate focusing optical power (prescription). If you are short or long sighted, your lens does not have the correct optical power. Spectacles or contact lenses can correct this error. You can also have your natural lens exchanged for an artificial lens of the appropriate prescription. This procedure also helps with presbyopia.
Mr. Nguyen can correct astigmatism and provide a person with both distance, intermediate (eg. desktop computer screen), and near vision (eg. reading a book, mobile phones) with the use of a premium multifocal intraocular lens. If you are interested please discuss this potential option at your consultation and Mr. Nguyen will advise on you on the type of intraocular lenses that suit your requirements.
Presbyopia is a natural refractive error where the ability to focus on near objects becomes all the more difficult as you age. It becomes increasingly more difficult to focus and you have to hold objects further and further away to see them properly. Presbyopia is believed to be caused by the hardening of the natural lens. The lens then loses its elasticity and the strength of the muscle fibre, causing focusing problems. Some may only experience near vision problems after the age of 45 but a number of people could have difficulty with focusing on near objects by their early 40s.
If you are 40 and older look out for the following symptoms and signs:
You do not need to be completely dependent on contact lenses or reading spectacles (bifocal or varifocal) if you have this refractive error. There are other vision correcting methods available. Exchanging your lens for a multifocal lens could improve your ability to focus.
Lens exchange has an advantage over laser eye surgery as it can give a permanent solution with unaided distance and near vision. Lens exchange is also sometimes called:
- Presbyopic Lens Exchange (Prelex)
- Refractive Lens Exchange
- Clear Lens Extraction
An additional benefit of IOL correction for presbyopia is that a patient won’t have to worry about developing cataracts later in life.
Over the past few years technology has improved to such a degree that there are a plethora of different intra ocular lenses and procedures to correct presbyopia. Depending on a patient's lifestyle, spectacle prescriptions and preference, not all eye surgery treatments will be appropriate. This means that a consultation with a consultant eye surgeon who specifically specialises in treating cataracts or presbyopia with these advanced lens implant designs is important.
The results will vary depending upon your vision, lifestyle and the anatomy of your eyes. Some patients find that they need glasses to read small type or drive at night. Most people, however, can go to the supermarket or conduct many of their day’s activities without depending on glasses, and only occasionally need to wear glasses.
