Spherical pIOLs were implanted in 328 (19.1%), and toric pIOLs were implanted in 1387 (80.8%) eyes during primary surgery. Nineteen eyes from 18 patients (1.107%) required exchange. Indications for pIOL exchange included high vault in nine eyes, low vault in two, and rotation of the pIOL in five. The mean follow-up period after the pIOL exchange was 3.3 months (range: 1\u20136.04 months). Repeat surgery was not required for any case. None of the patients had any residual refractive error, and their best-corrected visual acuity was preserved.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Overall, the rate of pIOL exchange in our study was low, and it is associated with good outcomes.
