Hello,
Thank you for your query at DoctorSpring.com
As far as degeneration is concerned , its good that laser was done . But some times after laser , their is liquefaction of vitreous jelly , so you see a floater , now as far as glare is concerned, you need a detailed check up like for any opacity in the lens . Kindly get a routine detailed examination. That is the only way to rule out an opacity.
Regards.
