Question
Hi,
I have undergone an eye surgery called Phaco two months ago.I had -3.0 Diopter in my Right Eye before the surgery but after the cataract surgery i need +1 Diopter for Distance and +3.0 for my Reading a newspaper.
Now i am worried about this number, i thought my near and far distance will get back to normal but i have landed with new problem. I only want to ask u that my surgery was successful of not?
Thanks
Answer
Thanks for your question
Natural lens has the ability to change its shape and thickness in order to accommodate for near and far distances and focusing light in the macula ( area of central vision in the retina ).
Patients who are older than 45 loss this ability to accommodate for near and this is called Presbyopia and in order to read, they need to have a reading glasses. The same thing happen to patient who underwent cataract surgery.
In cataract surgery, the natural lens (cataract) will be removed and replaced by standard intraocular lens which only can focus light from distance and patients can no longer see clearly for near distance. Most of people who underwent cataract surgery need glasses for near tasks such as reading and +3.00 Diaptor is within an acceptable range.
New Presbyopic intraocular lenses called premium intraocular lens or bifocal or multifocal IOL can be used instead of standard intraocular lens in order to correct for near, intermediate and far distances and in this case, the patients don't need near glasses.
he final far distance vision after cataract surgery will depend on many factors and +1.00 for far distance is an acceptable variation after cataract surgery. You can try Presbyopia or Multifocal Contact Lenses such as Acuvue Oasys for Presbyopia and Focus Dailies Progressive Contact Lenses.
