Dear Editor,We read the article titled “Anterior chamber intraocular lens - An effective alternative in traumatic and surgical aphakia in the era of scleral-fixated intraocular lens” by Mahapatra SK et al.,[1] published in the Indian Journal of Ophthalmology, with great interest. We want to congratulate the authors for the much-needed and excellent publication, but there are few issues that we would like to raise.First, there is no control group in the study. The authors have concluded that ACIOL has a lesser rate of complications such as IOL tilt, vitreous hemorrhage, and suture erosion compared to scleral-fixated IOL. However, in the methodology, they did not compare the results of ACIOL with scleral-fixated IOL. We felt that it is not worthy of making such conclusions against an established technique like scleral-fixated IOL without making the comparison.Second, there has been no mention of the anterior chamber depth in the preoperative workup of these patients. A deep anterior chamber is an essential criterion for ACIOL implantation. ACIOLs in a shallow anterior chamber (<2.8 mm) can lead to complications such as glaucoma, pseudophakic bullous keratopathy, cystoid macula edema, and finally, the need for an IOL explantation.[2]The authors did not look for endothelial cell counts in their follow-up period. Anterior chamber IOLs are more prone to cause pseudophakic bullous keratopathy or corneal decompensation. They did not mention anything regarding long-term endothelial loss following ACIOL implantation. We understand that as a community eye care center, it is difficult to implant scleral-fixated IOL in every case, but we also think that the conclusion made by the authors is not properly backed by the data or rationale.
