Purpose: To compare the refraction outcomes after phacoemulsification in high myopia implanted with and without a capsular tension ring. Material and methods: This retrospective study reviewed all patients with an axial length of 26 mm or more and had phacoemulsification with an intraocular lens (IOL) between January to December 2019. Pre-surgery biometric measurement and IOL power calculation were performed by the Barret Universal II formula. The chosen IOL power to be implanted with the predictive refractive outcome (PRO) was recorded. One month post-surgery, auto-refractive objective refraction in Spherical Equivalent (SE) was measured and compared to the PRO. Results: Fifty four eyes from 38 patients had a mean age of 57.15 + 9.73 (SD). In the non-CTR group, significant statistical difference between the pre to post-surgery outcomes of objective refraction was observed (p = 0.007), while in the CTR group there was no significant statistical difference (p = 0.830). The CTR achieved an accuracy of 0.01 D + 0.32 (p = 0.010) against -0.36 D + 0.55 in the non-CTR group. The CTR group, also reached 88.5% PRO for far
vision compared to 53.6% in non-CTR group (p=0.005). Conclusion: Phacoemulsification with CTR in high myopia resulted in better predictive outcomes.
