For these purposes PVP-I has been formulated at concentrations of 7.5–10.0% in solution, spray, surgical scrub, ointment, and swab dosage forms; however, use of 10% povidone-iodine though recommended, is infrequently used, as it is poorly accepted by health care workers and is excessively slow to dry.

[2] Early in Apt's career, eye surgeons commonly used sutures that were made of catgut or collagen ...
The specialist then sterilizes the eye and the surrounding area, often with povidone-iodine (PVP-I) solution, to prevent any infection in the injected site. [22] [31] Aqueous chlorhexidine is used instead in case of adverse effects to povidone-iodine. [23] Next, an eyelid speculum is placed to retract the eyelids and thus hold the eye open.
