“…In few reports, this suction effect has been noted to cause true ganglion cell damage resulting in visual field defects in some cases, which implies that any decrease in RNFL thickness after LASIK should be carefully evaluated. [ 21 22 23 24 25 26 ] This also suggests that the short term investigations published to date on apparent RNFL thinning due to refractive surgery should be extended with longer follow up in order to define the course of the apparent thickness variation during the postoperative period, and in particular to determine the time needed for the change to stabilize, and establish whether RNFL thickness/ONH measurements are usable for diagnostic and follow up purposes. Nevertheless, in most other related reports, there has been no evidence of RNFL thinning or glaucomatous damage at the ONH assessed by different imaging modalities after LASIK surgery.…”

Purpose:To determine whether photorefractive keratectomy (PRK) has a significant effect on optic nerve head (ONH) parameters and peripapillary retinal nerve fiber layer (RNFL) thickness measured by the Heidelberg Retina Tomograph 3 (Heidelberg Engineering GmbH, Heidelberg, Germany) in eyes with low to moderate myopia.Methods:This prospective, interventional case series, includes 43 consecutive myopic eyes which were assessed on the day of PRK and 3 months postoperatively using the HRT3. Among the stereometric parameters, we compared disc area, linear cup disc ratio, cup shape measure, global rim area, global rim volume, RNFL height variation contour and mean RNFL thickness; out of the Glaucoma Probability Score (GPS) we assessed changes in global value, rim steepness temporal/superior, and temporal/inferior, as well as cup size and cup depth before and after PRK.Results:Mean refractive error before and after PRK were −3.24 ± 1.31 and −0.20 ± 0.42 diopters, respectively. No significant change occurred in disc area, linear cup disc ratio, cup shape measure, rim area and rim volume among the stereometric parameters; and in rim steepness temporal/superior and rim steepness temporal/inferior in the GPS before and after PRK using the default average keratometry. However, RNFL height variation contour, mean RNFL thickness, and cup size and depth were significantly altered after PRK (P < 0.05).Conclusion:PRK can affect some HRT3 parameters. Although the most important stereometric parameters for differentiating normal, suspect or glaucomatous patients such as rim and cup measurements in stereometric parameters were not changed.

This report concerns the case of a 28-year-old female patient who was treated with topical steroids for 2 years following complicated hyperopic LASIK surgery with a re-treatment including a re-lift of the flap. A steroid-induced rise in the intraocular pressure (IOP) was subsequently observed on the treated eye, together with a glaucomatous subtotal destruction of the optic nerve, resulting in a residual vision of 1/15. An erroneously low IOP measurement, which was probably the reason for the delay in detecting steroid-induced glaucoma, has been reported in several cases concerning LASIK patients. The reason for the unusually severe course in the case in question can only be presumed, namely a possible accumulation of fluid at the interface or altered biomechanics following hyperopic LASIK surgery. The need for a thorough postoperative examination following refractive surgery must be emphasized. This case shows a cascade of complications following hyperopic LASIK surgery resulting in the functional blindness of one eye.
