Explantation of phakic intraocular lenses: causes and outcomes

Phakic intraocular lens explantation: series of 175 surgeries

“…[14][15][16] Previous studies report ECL as the cause for pIOL explantation in 20% to 67%. [7][8][9][10][11][12][13] PC pIOL have a lower rate of explantation due to ECL, but, in our study, it remains the cause in 14% of cases; therefore, these patients must be followed up with corneal endothelium assessment. Concurrently, Moya et al observed supraphysiological ECL in PC pIOL.…”

“…Overall, the main causes of explantation were cataract formation (44.0%) and ECL (50.3%), similar to the results reported in previous studies, where the rate of cataract as the reason for explantation varied from 35% to 71%. [7][8][9][10][11][12][13] Numerous mechanisms explain the premature development of cataract in this population: myopia which is by itself strongly associated with cataract development, surgical trauma, chronic inflammation and breakdown of the blood-aqueous barrier, crystalline lens touch during accommodation or eye rubbing, and changes in aqueous humor circulation. [14][15][16] Previous studies report ECL as the cause for pIOL explantation in 20% to 67%.…”

Accuracy of Intraocular Lens Calculation Formulas in Patients Undergoing Combined Phakic Intraocular Lens Removal and Cataract Surgery

“…4,17 Clinically significant cataract is the main reason for PIOL removal. [5][6][7] For eyes implanted with PIOL, the rates of PIOL removal combined with cataract surgery were 2-4% at 2 years, 10, 11 2-4.9% at 5 years, 4, 14 and 17-18.3% at 10 years. 4,17 We observed a longer interval between the PIOL implantation and cataract surgery in the AC-PIOL subgroup compared with the PC-PIOL subgroup.…”

“…4 Clinically significant cataract has been one of the main reasons for PIOL extraction in clinical practice. 5,6,7 Accurate ocular biometry measurement and IOL calculation are prerequisites of good visual quality after cataract surgery. It is known that measurement of preoperative anterior chamber depth (ACD), one of the key biometric parameters, could be affected by the presence of PIOL during applanation ultrasonography A-scan as well as IOLMaster examinations based on partial coherence interferometry (PCI).…”

Short-Term Efficacy and Safety of Cataract Surgery Combined with Iris-Fixated Phakic Intraocular Lens Explantation: A Multicentre Study

“…Some studies have reported good long-term outcomes up to 10 years [7][8][9]. However, some cases need pIOL explantation due to cataract formation or decreased endothelial cell density (ECD) [10][11][12]. Some studies have reported the safety and efficacy of combined cataract surgery/pIOL explantation; however, small case series [13][14][15][16][17] or case reports of new surgical techniques [18,19], except for the study by Vargas et al, investigated 87 eyes of 55 patients [20].…”
