Purpose
To analyze the clinical effects of patients with shallow anterior chamber depth(ACD＜2.80mm) after ICL and TICL V4C implantation.Let patients who have a shallow anterior chamber depth cannot undergo corneal laser surgery to choose ICL V4C with more confidence.
Setting
In China, the consensus of experts points out that the anterior chamber depth needs to be greater than 2.80mm in ICL implantation. However,In clinical work, we often encounter some myopic patients with shallow anterior chamber depth who are very eager to undergo ICL surgery. After fully communicating with the patient about the risks of Inappropriate lens size or high intraocular pressure after surgery, can the patient choose ICL implantation?
Methods
Retrospective clinical study. Patients who underwent ICL or TICL surgery in our hospital from January to December 2023 were collected.Inclusion criteria: anterior chamber depth <2.80, age 18 to 45 years old, completed 1-year follow-up period.The preoperative and postoperative visual acuity, refractive status, intraocular pressure, and corneal endothelial cell count were collected for statistical analysis, and the vault at each postoperative review was recorded.
Results
A total of 73 eyes with anterior chamber depth less than 2.80mm underwent ICL or TICL surgery and completed the 1-year follow-up period.There were 6 male eyes.The ACD was 2.34 to 2.79mm. The WTW was 10.6 to 12.3mm .One year after surgery, 82% of eyes had UCVA that was 1 line or more higher than the BCVA before surgery, and the effectiveness index was 1.29.The postoperative vault ranged from 100µm to 920µm, with an average of 403µm.Two of the eyes underwent replacement of a larger intraocular lens due to low vault after surgery.The postoperative IOP and number of endothelial cells was 13.96±3.05mmHg and 2949±364cell/mm2 ,which was not significantly different from the preoperative 14.75±3.19mmHg and 2962±359 cell/mm2(P＞0.05).
Conclusions
Among myopic patients, Female patients are more likely to have a shallow anterior chamber depth.Implantation of ICL or TICL remains very safe and effective in patients with shallow anterior chamber depth.
