Change in Intraocular Pressure Measurement After Myopic LASEK

Abstract

All tonometry methods measured a significant, but low, reduction of IOP 3 and 6 months after LASEK. Further change in visual acuity and IOP measurements between 3 and 6 months suggest a still ongoing postoperative process.

Intraocular pressure measurements with Goldmann applanation tonometry and dynamic contour tonometry in eyes after IntraLASIK or LASEK

“…A further study found the difference in preoperative and postoperative GAT measurements to be greater than in DCT measurements from eyes undergoing myopic LASEK, which is again consistent with the results of our study 12. Based on the results of the present study as well as previous ones, it seems that substantial reduction in postoperative central corneal thickness causes a significant underestimation of intraocular pressure measurement by GAT, whereas measurements obtained by DCT are apparently unaffected.…”

Can we trust intraocular pressure measurements in eyes with intracameral air?

“…ART is a recently developed tonometry method [11,16,17]. It is slit-lamp-mounted, and based on resonance technique.…”

Intraocular Pressure and Ocular Hypertension

“…Previous studies have reported that this tonometer can provide an overestimate in IOP values when compared to GAT [123][124][125]. Furthermore, it seems to be affected by CCT and corneal biomechanics [120,123,126]. Despite some advantages (repeatable and reliable measurements, no fluorescein is needed), the BioResonator ART has some drawbacks that may reduce its clinical usefulness, including: the need for a slit lamp, anesthetic and corneal contact, with sterilization issues; can be affected by various artifacts and measurement errors; moreover, its accuracy is influenced by the thickness and biomechanics of the cornea.…”

“…Recently, two reviews on the micropulse diode laser trabeculoplasty were published [125,126]. The reviews were conducted in a similar manner to SLT; however, a subthreshold micropulse diode laser technique as used that split up a continuous laser beam into on-and-off pulses to enable in-between cooling, similar to the micropulse modality of retinal micropulse laser treatment.…”
