In laser therapy, bright laser light enters the eye via a contact lens and creates small burns in the tearing area. Whereas when it comes to cryotherapy, an extremely cold probe is applied to the outer area of the eye to freeze the damage and heal accordingly.
To know which one you should opt for, you need to consult your cryo specialist and analyze all the aspects of your medical concern. After a thorough analysis, the specialist will suggest a treatment process that is more effective for your condition.
Both the surgeries are painless and are highly effective. However, your ophthalmologist should be the one deciding which process is best suited.
