Biochemical and immunological response of tears of 30 aphakic eyes half of which had received implants and the other half contact lenses.

The study included 30 aphakic eyes half of which had received implants and the remaining half contact lenses. The examination showed abnormal laboratory findings in the tears of these patients, with signs of inflammation in the frontal segment in a high percentage of implants: albumin showed pathological levels in 93% of the implanted eyes and total IgG was abnormal in 87% of the implanted eyes. For the contact lens group, the corresponding values were 69% and 50%. However, considering the advantages of implants, one should accept this even if it implies more frequent postoperative follow-ups. Careful attention should be paid especially to lysozyme, which was pathological in 27% of the implanted cases, but completely normal in the contact lens group.
