Many types of surgical corrections have been advocated to correct presbyopia. Among them are LASIK refractive surgery and cataract surgery with intraocular lens implants.
LASIK corrects the vision so one eye see far and and one eye sees near (Mono vision). This means reading with only one eye and seeing far with only one eye. This is good if the brain can adapt as there is loss of stereopsis vision and sense of depth which means driving and chopping food can be dangerous. It is also tiring to read with one eye.
There will also be the other side effects of LASIK (Eg: dry, red eyes). Presbyopia occurs as a result of early cataracts. Thus sooner or later, cataract surgery would have to be performed. In the process where cornea is thinned and reshaped, it means the option of intraocular multifocal lens may no longer be suitable for you in the future. You will thus be left with mono vision or glasses for life.
Cataract surgery and intraocular lens
About 20,000 cataract operations in Singapore are performed every year. This surgery involves removing one’s ageing natural lens and replacing it with an intraocular Lens (IOL). Intraocular means the lens is in the eye. They do not need to changed or replaced. They give convenience of good vision and last for life. Unlike the past, the only IOLs available were monofocal lenses. A monofocal IOL provides excellent vision but only at one fixed distance. This means you would still need to wear glasses when you are reading a book(near vision) and looking at the computer screen(intermediate vision).
Today, we are able to offer you the choice of a premium multifocal IOL.
Certain multifocal IOLs can correct both your distance vision or near vision and intermediate vision after cataract surgery. For the vast majority of patients, having a multifocal IOL means that you will be able to see at distance and up close without being dependent on glasses. So, patients choosing to have a multifocal IOL will likely find that they can drive, watch television as well as read a book and a computer screen without glasses. Over 95 % of our patients choose the multifocal IOL so we have a lot of experience with the different brands of IOLs.
