“…In ophthalmic surgery for diseases such as retinal detachment, retinopathy, and macular holes, part of the vitreous body needs to be removed and refilled with vitreous substitutes . Vitreous substitutes commonly used in the clinic include silicone oil and expandable gas. , Although they can structurally support the retina, they still have many unresolved shortcomings . First, their density is lower than that of the vitreous body, so patients are positioned face down for a long time after the operation.…”

Hydrogels are a type of functional polymer material with a three-dimensional network structure composed of physically or chemically cross-linked polymers. All hydrogels have two common features: first, their structure contains a large number of hydrophilic groups; therefore, they have a high water content and can swell in water. Second, they have good regulation, and the physical and chemical properties of their cross-linked network can be changed by environmental factors and deliberate modification methods. In recent years, the application of hydrogels in ophthalmology has gradually attracted attention. By selecting an appropriate composition and cross-linking mode, hydrogels can be used in different fields for various applications, such as gel eye drops, in situ gel preparation, intravitreal injection, and corneal contact lenses. This Review provides a detailed introduction to the classification of hydrogels and their applications in glaucoma, vitreous substitutes, fundus diseases, corneal contact lenses, corneal diseases, and cataract surgery.
