NBEO Ocular Disease Part 1 Practice Test

Tear film components interacting with the lens material create jelly bump deposits. Soft lenses are most prone because they’re made of hydrated, porous hydrogel or silicone hydrogel that readily absorbs tear proteins, mucins, and lipids. This absorption and the presence of mucus in the tear film allow these substances to coalesce on the lens surface into small, jelly-like bumps, especially with extended wear or longer use between cleanings. Rigid gas-permeable lenses, being less absorbent and having a different surface interaction with tears, don’t typically form these jelly-like deposits. Daily disposable lenses are replaced frequently, so there’s little time for such buildup to develop. Hybrid lenses can have a soft component, but the deposit pattern that leads to jelly bumps aligns with the properties of soft lenses, making them the most commonly associated type. Regular lens hygiene, appropriate wear schedules, and opting for daily disposables when appropriate help mitigate these deposits.
