Abstract
We examined postoperative corneal higher-order aberrations (HOAs) present after combined phacoemulsification with either microhook ab interno trabeculotomy (μLOT-Phaco) or goniotomy, using the Kahook Dual Blade (KDB-Phaco). Retrospective study: A total of 45 eyes underwent μLOT-Phaco and KDB-Phaco (LOT-Phaco) procedures, with 21 eyes that underwent cataract surgery alone used as controls. Visual acuity and corneal HOAs, coma-like aberrations, and spherical-like aberrations were analyzed before and at 1, 2, and 3 months after the surgeries. Risk factors that could potentially influence HOAs were evaluated. No significant postoperative changes were noted for corneal HOAs, coma-like aberrations, and spherical-like aberrations after cataract surgery alone. The mean corneal HOAs, coma-like aberrations, and spherical-like aberrations were 0.222 ± 0.115 μm, 0.203 ± 0.113 μm, and 0.084 ± 0.043 μm at baseline and 0.326 ± 0.195 μm (p < 0.001), 0.302 ± 0.289 μm (p = 0.03), and 0.150 ± 0.115 μm (p < 0.001) at 3 months after LOT-Phaco, respectively. Results of the analysis for risk factors suggested that a longer incision in Schlemm’s canal could influence corneal HOAs, coma-like aberrations, and spherical-like aberrations after LOT-Phaco. Although no significant postoperative changes were observed in corneal HOAs and coma-like or spherical-like aberrations after cataract surgery alone, a significant increase in corneal HOAs and coma-like or spherical-like aberrations remained after the LOT-Phaco procedure.
Highlights
Glaucoma is the leading the cause of blindness [1]
Phacoemulsification cataract extraction was performed in 21 eyes, with combined phacoemulsification with trabeculotomy performed in 31 eyes when using the microhook and in 14 eyes when using the KahookDual Blade (KDB)
−0.570 0.14 aberrations Recently, procedures using new microsurgical devices are being developed for minimally invasive glaucoma surgery (MIGS) [5,7]
Summary
Glaucoma is the leading the cause of blindness [1]. medication and laser therapy alone are used to try to decrease the intraocular pressure (IOP), incisional surgery is performed when these prove to be ineffective. Dual Blade (KDB; New World Medical, Rancho, Cucamonga, CA, USA), and microhook (Inami & Co., Ltd., Tokyo, Japan), in conjunction with 5-0 nylon sutures has been utilized during attempts designed to reduce the resistance of the trabecular meshwork from within the anterior chamber [4,5,6,7]. These techniques all fall within the designation of minimally invasive glaucoma surgery (MIGS) and can be performed by using procedures that utilize the iridocorneal angle from within the anterior chamber
