Abstract Details

Purpose:

Possibilities of using pointed applanation tonometer (I care pro) in patients after LASIK undergoing (early post-surgery period). Comparative analysis of data on the application of pointed applanation tonometer and traditional pneumotonometry on case of flap edema after LASIK.

Setting:

LLC “Dr. Kurenkov Clinic”, Moscow, Russia

Methods:

In the early post-surgery period LASIK patients require controlling IOP values if older than 40, glaucoma in family members or if using local/systemic corticosteroids. Conventional pneumotonometry is not applicable in the early post-surgery period after LASIK- intensive blinking may affect the flap. The corneal syndrome on day 1 after LASIK increases blinking rate (pneumotonometry), decreasing the measurement accuracy. Patients with no flap edema underwent pointed applanation tonometry since day 1 after LASIK (280 eyes, 142 patients). The second group of patients (flap edemas, 27 eyes, 16 patients) underwent IOP measurements using pneumotonometry and using the “Icarepro” tonometer since day 7.

Results:

Pointed applanation tonometry was easily tolerated by all LASIK patients since day 1 (142 patients of group 1), which allows for measuring IOP in the early post-surgery period (week 1). Tonometry data analysis in patients of the second group (edematic cornea) on day 7 after surgery shows differences in values for various tonometry methods. Pneumotonometry shows IOP values higher by 4.6 mmHg comparing to pointed applanaton tonometry. Thirteen patients noted that pointed applanaton tonometry is better tolerated, 1 has noted no difference, 2 patients preferred pneumotonometry. In group 1 pneumotonometry was not used before day 7, only “I care pro”.

Conclusions:

Using pointed applanation tonometry offers exciting possibilities in measuring IOP in the early post-surgery period after LASIK. Pointed applanation tonometry neither increases blinking nor causes negative sensations in the patients. In cases of corneal edema peumotonometry offers false-increased results. pointed applanation tonometry provides more accurate IOP values in cases of corneal edema. From a subjective point of view pointed applanation tonometry is tolerated much better comparing to pneumotonometry.
