註釋This chapter will explain the materials used in making intraocular lenses. Rigid IOL,Äôs made of PMMA have now given way to foldable silicone and acrylic lenses. This chapter will also throw light on the indications and contraindications for using each of the IOL,Äôs. The composition of each of the lenses, their water content, mechanical properties and their special ultraviolet absorbing features will be discussed in detail. The mechanism by which hydrophilic lenses are inserted through small incisions during cataract surgery will need a special mention. The problems with use of different types of intraocular lenses will also be dealt with.
