Abstract Details

Purpose:

To evaluate the safety & clinical outcome of Implantable collamer lenses (ICL) in patients of keratoconus.

Setting:

Nethradhama Super Speciality Eye Hospital

Methods:

Prospective, non randomised, non comparative, interventional study of ICL implantation in 67 eyes of 41 patients with keratoconus was carried out from January 2008 to December 2012 in a tertiary eye care centre .Progressive keratoconus was first stabilized with collagen cross linkage/ kera ring insertion. Minimum interval of 3months was kept between the stabilization procedure and ICL implantation. Data was collected pre op, at 3 months post C3R/ Keraring and at 6 month follow up visit after ICL implantation.

Results:

Out of the 67 eyes with keratoconus, 60 underwent C3R & 6 underwent Keraring insertion prior to ICL implantation. 18 (43.9%) were males and 23(56.1%) were females. Patients were in the age group of 19 – 41 years with majority 17 (41.46%) in the age group of 24 – 28 years. Preop refractive error varied from spherical equivalent of -1.62D to -25D, with mean spherical equivalent of – 9.75D. 30 eyes (44.78%) had pre op spherical equivalent between -5.25D to -10D. 9 eyes (13.43%) had pre op BCVA of 6/6 whereas 29 eyes (43.28%)had post op UCVA of 6/6.Post surgery V/A showed 1 line improvement in 18 (26.87%) eyes, 2 line improvement in 6 (8.96%) eyes, 3 line & 4 line improvement in 2 (2.99%) eyes each. V/A was status quo in 37 (55.22%) eyes and 2 (2.99%) eyes showed deterioration of V/A.1 eye had secondary glaucoma and the 1 had keraring infiltrates. Average interval between C3R / kera ring and ICL implantation was 367 days.

Conclusions:

Implantation of ICL following stabilization of keratoconus with C3R or Keraring is a safe and effective option. Hence ICL is a much awaited definitive and rewarding form of treatment in patients with keratoconus.
