Purpose
To accurately select the model and placement of ICL intraocular lens, reduce the post-ICL alignment rate and replacement rate, and explore the feasibility of personalized ICL surgery.
Setting
Group A and group B were divided into two groups according to the selection of ICL human intraocular lens model and placement position. In group A, 118 patients with 236 eyes undergoing ICL surgery from July 2020 to November 2020 were randomly selected.
Methods
ICL intraocular lens model was selected according to STARR's OCOS table, and ICL intraocular lens was placed horizontally. In group B, 97 patients with 193 eyes who underwent ICL surgery from December 2020 to March 2021 were randomly selected. By making an improved OCOS table, combined with accurate measurement of STS with different coaxial positions, ICL intraocular lens model and placement position were accurately selected, and the 6-month arch height and postoperative alignment rate replacement rate of group A and group B were compared for retrospective study.
Results
The number of cases with arch height <250um 6 months after operation in group A and B is 39 eyes (16.53%) and 19 eyes (9.84%) . The difference is statistically significant (P<0.05): The number of cases of 250um≤ arch height ≤750um in group A and B 6 months after surgery is 187 eyes (79.24%) and 172 eyes (89.12%) , with no statistically significant difference (P>0.05). There are 10 eyes (4.24%) in group A and 2 eyes (1.04%) in group B with arch height >750um 6 months after operation, and the difference is statistically significant (P<0.05). In 18 cases of group A, the rate of secondary operation is 7.63%. In 3 cases of group B, the rate of secondary operation is 1.55%. There is significant difference in the rate of second operation (P<0.05).
Conclusions
By making an improved OCOS table, combining with accurate measurement of STS with different coaxial positions, balancing various factors affecting the arch height after ICL operation, accurately selecting the ICL crystal type before surgery, determining the CL placement position, and obtaining a more ideal arch height, reducing the alignment rate and replacement rate of ICL implantation surgery.A new approach for ICL personalized surgery was explored with good clinical effect.
