Timeline
Interventions
The eye will be topically anesthetized with 0.5% proparacaine drops and 4% lidocaine drops and a 10% povidone-iodine scrub of the lids and lashes will be performed. A sterile speculum will be placed between the lids. Five percent povidone-iodine drops will then be applied over the ocular surface followed in three rounds by additional 5% povidone iodine and a sterile cotton swab soaked in sterile 4% lidocaine applied with gentle pressure to the area designated for injection in the infero-temporal quadrant.
The eye will be topically anesthetized with 0.5% proparacaine drops and 5% povidone iodine will be placed over the eye. Two drops of preservative-free 3.5% lidocaine hydrochloride ophthalmic gel will be placed into inferior conjunctival sac. The patient will be asked to close the eye for 7 minutes. Next, a 10% povidone-iodine scrub of the lids and lashes will be performed. A sterile speculum will be placed between the lids. Five percent povidone-iodine drops will then be applied over the ocular surface and allowed to remain in contact with the eye for at least 2 minutes. The eye will then be rinsed with antibiotic drops.
