Intraocular lenses (IOLs) take a vital part in cataract surgery. Together with the developments in cataract surgery, innovations are seen in IOLs. After cataract surgery the aim is to correct near visual acuity and astigmatism besides distant vision, this can be possible with new generation IOLs. The patients need to be informed about IOLs. Expectations of patients must be learnt, and possible outcomes should be explained them in detail. Surgeon‘s experience and information is important in preoperative preparation period and in decision of IOL according to patient needs. Today numerous IOLs are commercially available. As is known, it is hard to classify IOLs. In this review, our effort was to bring in an approach to classify IOLs of different properties. While classifying IOLs, we kept optic properties in the forefront; but some IOLs have been classified according to their other properties such as physical properties and location of implantation. According to optic properties, we described monofocal, multifocal, toric and accomodative lenses. According to other properties, chromophore, spheric, aspheric, anterior chamber and iris-claw IOLs are discussed. We tried to keep the classification simple and easy to understand. But, one should keep in mind that with recent technologic developments this classification may change and new IOLs may be added. In this review, it was mentioned about IOLs which are started to use more frequently in opthalmology pratice and their classifications.
