A detailed ophthalmic examination was done in all the cases. Horizontal corneal encroachment of pterygium from the limbus was measured. Keratometry and biometric measurements were performed preoperatively to determine the target refraction which was kept between \u2212 0.50D and + 0.50D. The achieved spherical equivalent (SE) and prediction error were calculated postoperatively. A difference of &gt;\u00b1 1.00D SE from the targeted postoperative refraction was considered a refractive surprise.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>The mean age of patients was 61 \u00b1 8.32 years. The mean extension of pterygium on the cornea was 2.3 \u00b1 0.91 mm. Refractive surprise was seen in 16.7% of cases of cataract with pterygium and 10% of cases of cataract without pterygium.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
