CELL REACTION AND PIGMENT DEPOSITS ON THE POSTERIOR CHAMBER INTRAOCULAR-LENS

Cellular reaction and pigment deposits on the intraocular lens were ev aluated by biomicroscopy in 220 eyes which had undergone estracapsular cataract extraction and implantation of a posterior chamber intraocul ar lens 3 months previously. No cells or pigment were observed on the intraocular lens in 32% of the eyes, while small cells and/or pigment were found in 32% and giant cells with or without pigment and small ce lls were seen in 35%. In a sample of 28 eyes the clinical findings cor related with the findings in specular microphotographs. The correspond ing percentages were 32, 36 and 32% in biomicroscopy and 14, 36 and 50 % in specular microphotography. The giant cell reaction was notably (p < 0.001) associated with the presence of exfoliation. Previous ocular diseases and operations did not increase the frequency of cellular re action.
