From: Reasons for explantation of phakic intraocular lenses and associated perioperative complications: cross-sectional explant registry analysis

Cause Number of cases (percentage)
Group 1, N = 34 Group 2, N = 28 Group 3, N = 7
Cataract 12 (35.3) 14 (50) 3 (42.9)
Cornea-related 9 (26.5) 3 (11)  
Cataract combined with corneal damage 9 (26.5) 5 (18) 1 (14.3)
Type of Cataract
Anterior subcapsular 2 (10)  1 (25)
Cortico-nuclear 5 (24) 7 (37)  
Nuclear 10 (47) 5 (26) 2 (50)
Posterior subcapsular 4 (19) 7 (37) 1 (25)
Type of corneal damage#
Corneal decompensation 2 (11)   
Low ECC 6 (33) 1 (12)  
Endothelial damage 10 (56) 7 (88) 1 (100)
Uveal tissue-related 4 (11.8) 6 (21)  
Type of uveal-relation
PIOL subluxation due to haptic de-enclavation   5 (83)  
Optic decentration due to haptic migration 2 (50)   
Chronic iridocyclitis 2 (50) 1 (17)  
Oversizing (leading to intermitted IOP increase and pigment dispersion)    1 (14.3)
Photopic phenomena    2 (28.6)
  1. pIOL phakic intraocular lens, ECC endothelial cell count, IOP intraocular pressure; # divided into three subcategories: Corneal decompensation was chosen if keratoplasty was required, low ECC if the number of cells prior to explantation was below 1500 cells/mm2. Endothelial damage: the presence of abnormal endothelial cell morphology but Low ECC and corneal decompensation are absent
