Clinical & Coding Specifications
Clinical Context
A 72-year-old patient who previously underwent extracapsular cataract extraction without placement of a permanent intraocular lens presents for planned intraocular lens (IOL) implantation to restore refractive function. The patient arrives at an ambulatory ophthalmic surgical center after preoperative evaluation including visual acuity testing, slit-lamp exam, intraocular pressure measurement, and biometry for IOL power calculation. On the day of service the surgeon confirms the eye is ready for secondary IOL insertion under topical or regional anesthesia. The procedure includes opening the prior surgical site or making a new corneal/limbal incision, entering the capsular bag or sulcus as appropriate, inserting and positioning the IOL, and verifying centration and wound integrity. Postoperative care includes topical antibiotics and steroid drops, brief observation in the recovery area, and a follow-up visit within one week to assess visual outcome and wound healing.
