When preparing for the SSC CGL exam, especially for a role like Assistant Section Officer (ASO) in the Central Secretariat Service (CSS), candidates must meet specific medical standards. The SSC CGL medical examination includes tests for vision, and the use of corrective measures such as spectacles or contact lenses is typically allowed. However, when it comes to advanced procedures like Implantable Collamer Lens (ICL) surgery, the situation is less clear-cut.

The SSC CGL medical guidelines do not specifically mention ICL, but they do focus on ensuring that the candidate has the necessary vision standards for the job. ICL surgery is a corrective procedure often chosen by individuals who are not suitable candidates for LASIK. Since the purpose of ICL is to correct vision, it may be considered similar to wearing contact lenses or glasses.

However, the final decision rests with the medical board conducting the examination. They may assess whether the ICL meets the required vision standards without complications that could affect job performance. Therefore, it is recommended to get clarity directly from the SSC or the relevant medical authority by submitting a query or consulting a medical professional experienced with SSC medical examinations.

It's always better to have a thorough understanding of the specific medical requirements for the post you're aiming for.
