Worked example
Fictional case: Mrs. L.K., 45 years, right eye dense central corneal scar 5 mm across after healed microbial keratitis 1 year ago, no active infection, no vessels in the central 8 mm. Vision counting fingers 1 m. Clear lens.
Case details
Date: 14/07/2026. Elective (donor tissue available). Eye OT 3.
Block 09:15. Incision 09:35. End 10:50.
Surgeon: Dr C. (consultant, cornea). Assistant and part of suturing: Dr A. (3rd-year resident). Scrub nurse: Sr E. Anaesthetist on standby: Dr D.
Indication and pre-op
Right eye: CF 1 m, projection accurate. Central stromal scar 5 x 4.5 mm, 80% depth. Periphery clear, no vessels. Clear lens. IOP 14 mmHg. B-scan: retina attached, vitreous clear.
Indication: optical penetrating keratoplasty. Lids normal, Schirmer's normal, corneal sensation present.
Donor: eye bank ID ________, donor 58 years, death-to-preservation 4 hours, stored in McCarey-Kaufman medium since 13/07/2026, endothelial cell count 2,650 cells/mm2, serology screen negative as per eye bank form.
Consent: general, procedure-specific and anaesthesia consent from the patient in Hindi, including rejection, long-term drops and need for glasses or contact lens.
Right eye marked. WHO checklist sign in and time out done. Pupil constricted with pilocarpine drops before surgery.
Anaesthesia and position
Peribulbar block, right eye, 7 ml of 2% lignocaine and 0.5% bupivacaine (2:1) with hyaluronidase 5 IU/ml and adrenaline 1:100,000. Compression 15 minutes, eye soft. Supine. Lids painted with povidone-iodine and draped. Wire speculum.
Procedure
Superior and inferior rectus traction sutures with silk 4-0.
Host cornea measured with calipers. Trephine size 7.5 mm chosen to include the whole scar.
Donor button punched from the endothelial side on the cutting block with a 7.75 mm trephine (0.25 mm larger than the host), covered with medium. Medium clear; sample sent for culture.
Paracentesis at 9 o'clock with a super-sharp blade. Visual axis marked with an inked Sinskey hook, radial marker applied for suture placement.
Hand-held 7.5 mm trephine, centred on the visual axis, cut to about 80% depth. AC entered with a super-sharp blade. Host button excised with right- and left-cutting corneal scissors, edge regular. Button sent for HPE.
Viscoelastic placed over iris and lens. Lens clear and untouched. No synechiae.
Donor button placed on the viscoelastic bed. Four cardinal interrupted nylon 10-0 sutures at 12, 6, 3 and 9 o'clock, even tension, diamond pattern seen.
Twelve further interrupted nylon 10-0 sutures placed, 16 in all. Knots buried.
Viscoelastic washed out with BSS through the paracentesis. AC formed, wound watertight.
Surgical keratometer: round mire. Traction sutures removed.
Closure
Subconjunctival antibiotic and steroid injected (drugs and doses as charted by Dr C.). Pad and shield.
Specimens and implants
Host button 7.5 mm in formalin for HPE, labelled, with requisition.
Donor medium sample sent for culture.
Eye bank donor label pasted in this note. No IOL.
End of procedure
Blood loss negligible. No complications.
Needle and instrument count correct.
Shifted to ward. Pulse 82/min, BP 128/80 mmHg.
Post-op orders
Do not rub or press the eye.
Pad off tomorrow morning. Examine graft, wound, AC and IOP.
Topical steroid and antibiotic drops as written on the drug chart by Dr C., with the taper plan.
Explained warning signs of rejection and infection: redness, light sensitivity, blurred vision, pain. Come to eye casualty the same day.
Follow up in cornea clinic as per schedule. Sutures to be removed only by the cornea team.

Must document for this operation
- Host and donor trephine sizes. Donor-host disparity affects refraction, and a regraft is planned from these numbers.
- Donor details: eye bank ID, age, time from death to preservation, medium, endothelial count. If the graft fails early or an infection is traced to the donor, the eye bank needs the donor ID.
- Number and type of sutures (interrupted, running, or both). Selective suture removal to reduce astigmatism depends on knowing the pattern.
- Host button sent for HPE (and for culture when the graft is for infection), and donor medium sent for culture. An infection after the graft is treated on these results, and the HPE confirms the diagnosis.
- Lens status and any intraocular work (iridectomy, vitrectomy, IOL). Tells the next surgeon what is behind the graft before any cataract or glaucoma surgery.
- History of herpes simplex and whether antiviral cover was started. Recurrence of herpes in a graft without antiviral cover is a known cause of failure.
Common mistakes in these notes
- Writing only 'PK done' without trephine sizes.
- No donor ID or eye bank label in the note.
- Not recording the number of sutures.
- Not stating where the host button was sent, or that the donor medium went for culture.
- Not recording the lens status at the end.
Indian practice and paperwork
- NABH expects the operative note to be written before the patient is moved out of recovery, and post-op care to follow a written plan. For a graft, the drop schedule and taper should be written. (NABH 5th ed., COP.14(e) and (f))
- Consent must cover risks, benefits, alternatives and who will do the operation, in a language the patient understands. Write who operated if a resident sutured part of the graft. (NABH 5th ed., PRE.4(c))
- The host button goes for HPE in formalin with a requisition. Discarded formalin is chemical waste in the yellow (f) category. (Bio-Medical Waste Management Rules 2016, CPCB guidelines)
