Clinical observation of the axial length and corneal curvature after silicone oil removal combined with cataract surgery in high myopia patients

Abstract

AIM: To explore the postoperative axial length(AL)and corneal curvature(K)shift in high myopia silicone oil patients complicated cataract after silicone oil removal combined with cataract surgery as well as the relationship.METHODS: From August 2020 to November 2020 in the Affiliated Eye Hospital of Nanchang University, 45 patients(48 eyes)with silicone oil eye complicated cataract were divided into 2 groups: 20 eyes of 20 patients(refraction ≥-6.00D and AL ≥26mm)in high myopia group and 28 eyes of 25 patients(refraction 0.05). The AL of the patients in the high myopia group was 28.35±1.68mm after silicone oil removal combined with cataract surgery, which was shorter than 28.08±1.53mm before the operation(P0.05). The median ΔAL of patients in the high myopia group was [-0.28(-0.44, -0.08)] compared with the non-high myopia group [-0.06(-0.20, 0.15)], which was statistically different(P0.05). There was no correlation between |ΔAL| and |ΔK|, or and preoperative K values(P>0.05)in two groups. Preoperative AL was moderately positive correlated with |ΔAL| in the high myopia group(r=0.702, P=0.01), but not in the non-high myopia group(P>0.05).CONCLUSION: There was no significant shift in K value of high myopia group with silicone oil eye complicated cataract after the silicone oil removal combined with cataract surgery. The longer preoperative AL in high myopia group, the more likely become shorter after surgery, meanwhile the longer AL, the greater AL shift.
