Follow-up of 439 Federov Mark I lenses implanted after ICCE, with rationale for change and comparative results at one year.
This paper presents the sight threatening complications at one year (439 eyes), four years (320 eyes) and seven years (106 eyes) following ICCE with Federov Mark I lens implantation, together with my rationale for change to the Choyce Mk IX following ICCE and the Pearce Equilimb lens following ECCE. The problems with the Federov Mark I lens relate: (i) to its design, needing a widely open section for insertion; (ii) iris support which provides mobile fixation with potential for macular oedema, retinal detachment, corneal touch and decompensation and eventual iris disintegration with lens dislocation. The complications at one year are then compared with those using 176 Choyce Mk IX and 113 Pearce Equilimb lenses.
