Güra gaç, M.D., Semra Acer, M.D., and _ Ibrahim F. Heps ¸en, M.D. Objective: To quantify the difference between anterior chamber parameters determined by the Galilei dual Scheimpflug analyzer after uneventful cataract surgery in normotensive eyes. Methods: In this study, 39 eyes of 30 patients (11 men and 19 women) who had uneventful cataract surgery with phacoemulsification were evaluated preoperatively, and at 1 month postoperatively with the Galilei. We investigated the measurements including anterior chamber depth (ACD), anterior chamber angle (ACA), anterior chamber volume (ACV), central corneal thickness (CCT), and the 3-, 5-, and 7-mm corneal thickness (CT) preoperatively and postoperatively. Results: The differences between ACD (P=0.01), ACA (P=0.07), ACV (P=0.01), and 7-mm CT (P=0.01), and intraocular pressure (P=0.03) were statistically significant after the first month of phacoemulsification. How- ever, the differences between CCT (P=0.60), 3-mm CT (P=0.75), and 5-mm (P=0.17) CT were not statistically significant. Conclusions: After the first month of cataract surgery, a significant increase was observed in ACD, ACV, ACA, and 7-mm CT parameters, which were practically determined by a new noncontact Scheimpflug imagining system. Key Words: Anterior chamber depth—Anterior chamber angle—Anterior chamber volume—Corneal thickness—Galilei—Phacoemulsification. (Eye & Contact Lens 2015;41: 40–43) P revious studies have reported that cataract surgery leads to an increase in the anterior chamber and the anterior chamber angle (ACA). 1,2 Several quantitative methods for measuring these anterior chamber parameters are available. 3,4 These methods may be based on the scanning-slit optical pachymetry (Orbscan, Bausch & Lomb, Rochester, NY), single rotating Scheimpflug camera (Pentacam, Oculus, Wetzlar, Germany), and a dual rotating Scheimpflug–Placido hybrid camera system (Ziemer Ophthalmic Systems AG, Zurich, Switzerland). 5 The Galilei topographer uses a double Scheimpflug system combined with a Placido disk. The double Scheimpflug system was designed with 2 cameras 180 degrees apart in an effort to compensate for error associated with scans at an oblique angle. The Galilei system uses the Placido disk to analyze the anterior curvature; however, the Pentacam uses the Scheimpflug images only. Furthermore, the dual Scheimpflug sys- tem provides exact pachymetric measurements of the central and the peripheral cornea, even in micro movements of patients. 6 In this study, we evaluated the difference between anterior chamber measurements, including anterior chamber depth (ACD), ACA, anterior chamber volume (ACV), central corneal thickness (CCT), and the 3-, 5- and 7-mm corneal thickness (CT), determined by the Galilei dual Scheimpflug analyzer after uncomplicated phacoemulsi- fication in normotensive eyes. METHODS In this prospective study, we evaluated 39 eyes of 30 patients who underwent uncomplicated cataract surgery with phacoemulsification and intraocular lens (IOL) implantation between 2011 and 2012 at Turgut Özal University Hospital. Patients with a history of intraoc- ular surgery, and any ocular diseases, such as pseudoexfoliation syndrome, uveitis, and glaucoma were excluded from the study. The study was conducted in accordance with the ethical standards stated in the 1964 Declaration of Helsinki. The study was approved by the Local Ethics Committee of the participating center. Topical anesthesia was used to perform all phacoemulsification and IOL implantation procedures. The surgery was performed through a 2.8-mm clear corneal incision. After phacoemulsification and aspiration, foldable IOL was implanted in the capsular bag. The Rayner Superflex hydrophilic acrylic IOL (Rayner Superflex, Rayner Intraocular Lenses Limited, United Kingdom) with a 6.25- mm optic diameter and 12.5-mm overall length was implanted in all patients. The postoperative regimen included topical moxiflox- acin 4 times a day for 1 week and 1% topical prednisolone acetate 4 times a day for a period of 4 weeks. All patients had routine ophthalmic examinations including visual acuity, slit-lamp biomicroscopy, tonometry, and fundo- scopy. Intraocular pressure (IOP) was measured with the Gold- mann applanation tonometer. The Galilei uses a dual rotating Scheimpflug camera integrated with a Placido disk topographer. The device’s software (Galilei G2, version 5.2.1) was used to perform measurements. The flash illu- mination is an output from a 475-nm blue LED (ultraviolet-free), and it measures more than 122,000 data points per scan. The simultaneously recording dual cameras are purported to produce more reliable pachymetry and posterior curvature data than From the Department of Ophthalmology (R.Y., S.A.), Pamukkale University Medical School, Denizli, Turkey; Department of Ophthalmology (E.G.), Ercis ¸ State Hospital, Van, Turkey; Department of Ophthalmology (B.F.G.), Turgut Ozal University Medical School, Ankara, Turkey; Depart- ment of Ophthalmology (F.U.), Trabzon Arakli Bayram Halil Devlet Hasta- nesi, Trabzon, Turkey; and Department of Ophthalmology (I.F.H.), Gazi University Medical School, Ankara, Turkey.
