This is a complication of contact lens overwear. This can be very painful. The white dots are collections of white blood cells. Eventually the cornea can ulcerate in those areas and the patient becomes unable to wear contact lenses any longer, without treatment. Treatment is prescription anti-inflammatory and antibiotic drops, a good pair of glasses with the current prescription, and better contact lenses. The bottom picture is what the cornea looked like on the day of presentation. The top picture is 5 days after treatment. This patient had been wearing Acuvue Oasys lenses. We changed her to better quality lenses that have less incidence of marginal keratitis.
