Based on the method of fixation IntraOcular advantages
Anterior chamber IOL (Angle supported IOLs). .g., ‘Kelman multiplex (IOL)’.
Iris-supported lenses e.g., Singh and Worst’s iris claw lens.
Posterior chamber lenses
Depending on the material of manufacturing
Rigid IOLs - PMMA
Foldable IOLs - silicone, acrylic
Rollable IOLs - hydrogel
Based on the focussing ability the IOLs are of following types:
Unifocal IOLs
Multifocal lOLs
Accommodative IOLs
Aphakic versus phakic refractive IOLs.
Special function IOLs
Toric IOLs astigmatism
Aspheric IOLs.
Aniridia IOLs

Malpositions decentration
• Sunset syndrome (Inferior subluxation of IOL).
• Sunrise syndrome (Superior subluxation of IOL).
• Lost lens syndrome refers to complete dislocation
of an IOL into the vitreous cavity.
• Windshield wiper syndrome. It results when a very
small IOL is placed vertically in the sulcus. In this
the superior loop moves to the left and right, with
movements of the head.
