Purpose To perform increased intraocular pressure (IOP) screening in non‐glaucomatous patients after deep anterior lamellar keratoplasty (DALK) due to keratoconus with normal IOP measured during control visits. Methods Ten non‐glaucomatous patients, who underwent DALK procedure due to keratoconus were included into study. Patients were measuring IOP using self‐tonometer Icare One (Icare, Finland) continuously for 30 days, 3 times per each day. Additionally patients were checked by ophthalmologist 3‐times during follow‐up time in Outpatient Clinic, where applanation tonometry and central corneal thickness measurements were performed. After 30‐days, self‐measured IOP was evaluated for rises above 21 mmHg as well as rises above mean GAT values measured during control visits. Results Mean IOP measured with GAT and adjusted according to CCT was 15 mmHg and ranged between 11 and 19 mmHg. There were no values above 21 mmHg reported during follow‐up time. In Icare One measurements, all patients showed incidents of IOP values higher than measured with GAT, however mean values ranged between 10‐18 mmHg. Six out of 10 patients revealed to have IOP elevations higher than 21 mmHg between control visits (with maximum values up to 46 mmHg), and this elevated values constituted from 3.3 up to 20.0 % of all self‐measurements. Conclusion Self‐tonometry with Icare One might be useful tool to identify patients who develop undetectable IOP increases between control visits. This can help in prevention of vision loss and transplant procedure failure in DALK patients.
