  1. Second generation: Collamer™ (?) Fyodorov lens

  2. Third generation: Staar ICL -Material: Hydrophilic collagen polymer (63% hydroxy-ethyl-methyl-acrylate; 0.2% porcine collagen; 3.4% benzofenone for UV absorption) -Water content: 34% -Refractive index: 1.45 -Optical zone: 4.5-5.5 mm -11.0-13.0 mm long; 7.0 mm wide -Thickness: 50 mm at the optic zone; 500-600 mm at the haptic zone; 100 mm at the haptic footplates

  3. Third generation: Staar ICL

  4. Third generation: Medennium PRL -Material: Highly purified silicone -Refractive index: 1.46 -Optical diameter: 4.5-5.0 mm -10.8 or 11.3 mm long -6.0 mm wide -“One-size-fits-all” design -Not fixed in the ciliary sulcus; “floating” on the natural crystalline lens

  5. Third generation: Medennium PRL

  6. Phakic posterior chamber IOLs • Cells involved in crystalline lens and capsular bag opacification • Evolution of designs of PPCIOLs • Relevant aspects of fixation and sizing • Sizing issue: New studies • Surgical implantation • Relationship between cataract and myopia • Cataractogenesis • Specimens analyzed in our Center • Mechanisms • Review of the literature • Classification of cataracts after phakic IOL implantation?

  7. Second generation: Chiron-Adatomed silicone lens

  8. Second generation: Chiron-Adatomed silicone lens

  9. Third generation: Staar ICL -Consecutive “V” models with different vaulting characteristics in order to reduce the possibility of cataractogenesis -Correct lens sizing is important: too large excessive vaulting too small instability/decentration
