Posted on Mon, 18 May 2015
Question: I had cataract surgery 1 year ago. toric lenses were implanted. I have been experiencing the issue of seeing dark halos in my peripheral vision during the day, growing more pronounced as the brightness of the light increases. I do not have any issue with night time vision or night driving. I have brought this to the attention of an optometrist and 2 ophthalmologists and I can't seem to get anyone to listen to me or give me a straight answer as to what is going on.

Brief Answer:
These dark halos are because of edge of intraocular lenses.

Detailed Answer:
Hello
Welcome to Health care magic

I reviewed your history.
These symptoms of seeing dark halos in the peripheral vision following implantation of intraocular lens. These are because of edges of intraocular lenses andare seen in all with intraocular lenses.
These are more pronounced with toric lenses and multifocal lenses.

However these will decrease because of neuroadaptation.

There is no effective treatment for this condition. Decreasing the size of pupil or use of dark glasses will be of help.
Hence try these things and do discuss this with your ophthalmologist or optometrist.

Hope I have answered your question and the information is helpful to you.
Do write back to me for further questions.

Thank you

Brief Answer:
Larger lenses does not cause these problems.

Detailed Answer:
Hello
Thank you for the follow up question.

Use of bigger intraocular lenses lead to lesser incidence of these problems.
But these lenses require bigger incision and poor vision following their insertion.

Hence smaller lenses are used for quick rehabilitation of vision.
