Abstract
Purpose
To evaluate the effects of chalazion surgery on intraocular pressure (IOP) and the biomechanical, topographic, and topometric properties of the cornea.
Methods
A total of 29 patients with upper eyelid chalazion were included in this study. All patients underwent preoperative and postoperative detailed ophthalmological examinations including scale of chalazion size; IOP (IOPcc and IOPg), corneal hysteresis, and corneal resistance factor measurements using ocular response analyser (ORA; Reichert Instruments, Depew, NY, USA); topographic and topometric properties of the cornea using Pentacam HR (Oculus GmbH, Wetzlar, HE, Germany). Preoperative and postoperative measurements were compared.
Results
The mean age of the patients was 29.07 ± 13.74 years (18–54 years). The mean IOPcc was 15.82 ± 4.20 mmHg preoperatively and 14.72 ± 3.96 mmHg postoperatively, and the mean IOPg was 15.21 ± 3.91 mmHg preoperatively and 14.21 ± 4.02 mmHg postoperatively (p = 0.020, p = 0.007, respectively). The mean central keratoconus index (CKI) was 1.006 ± 0.01 preoperatively and 1.002 ± 0.01 postoperatively (p = 0.035). Other biomechanical, keratometric, topographic, and topometric parameters were similar before and after the surgery (all p > 0.05).
Conclusion
To the best of our knowledge, this is the first report to suggest that IOP and CKI are decreased after the removal of upper eyelid chalazion.
