Experimental Treatment
Placebo Group
Group I: Subcut. + Subconj. InjectionExperimental Treatment2 Interventions
Patients will undergo standard blepharoptosis repair using an anterior approach, with an added injection of local anesthetic (Xylocaine) beneath the conjunctiva of the lid being operated on. They will still receive the standard subcutaneous local anesthetic given during blepharoptosis repair.
Group II: Subcut. + Sham Subconj. InjectionPlacebo Group2 Interventions
Patients will undergo standard blepharoptosis repair using an anterior approach, however they will not receive the additional subconjunctival Xylocaine injection. Instead, they will receive a sham injection of Normal Saline to prevent them from knowing which eye received the additional anesthetic.
