Welcome to Just Answer:
It appears that she is experiencing dry cornea from residual inflammation from the surgery. In general, the inflammation of the surgery can often take up to 4 weeks to completely resolve, sometimes a little more if the cataract was dense, which may cause more trauma to the eye during removal. It is usually recommended that the drops, steroid, non-steroid and tear drops be used up to 4 weeks after surgery, but with tapering dosage, in order to allow complete resolution of the background inflammation. This often prevents the corneal dryness
and the affect on refraction
. If she has the cornea spotting, that will affect her glasses prescription. It is best to clear it before getting the final glasses.
In general, the cornea tends to dry more during the period of recovery as the tear film
is much thinner. Now, it is important to exclude that she has not developed any scar tissue on the lens which require wiping off with laser. If that is the case, it can be cleaned after 6 weeks at least so as to ensure all has formed. The can occur if the inflammation after the surgery was not poorly controlled. I suggest that she follow-up with her doctor and request for evaluation for any development of scar tissue from inflammation after surgery.
In addition, to speed the resolution of the corneal spotting, aggressive use of tear drop (preservative free - such as Refresh or Genteal). Also, she should be evaluated for any blephritis (inflammation of the eyelids) which can often be the source of the spotting. This can be treated with doxycycline 100 mg orally twice daily for 14 days in addition to gentle eyelid hygiene with diluted baby shampoo. In about 2-4 weeks her eyes should be more better for very good refraction for glasses. In general, the management of after lens replacement depends on the individual patient.
