Abstract： Objective To investigate quantitative changes of the anterior segment configuration after clear corneal incision phacoemulsification and foldable intraocular lens (IOL) implantation with slit-lamp-adapted optical coherence tomography (SL-OCT). Methods In prospective consecutive case series, clear corneal incision phacoemulsification and foldable intraocular lens implantation were performed in 44 eyes of 40 patients. The changes of the anterior segment configuration were performed by SL-OCT before and 1 day, 1 week, 2 weeks and 1 month after surgery. SPSS 16.0 software was used to analyze statistical difference. Results For all patients, the central corneal thickness (CCT) and the incisional corneal thickness (ICT) increased significantly 1 day after surgery ( CCT increased 99. 59 μm, ICT increased 234. 57 μm;P = O. 490). At 1 month, the CCT almost had returned to baseline, but the ICT had been ticker about 19. 25 μm than baseline (P=0. 001) . The measurements of ACD, AODS00, AOD750, TISAS00, TISA750 also increased significantly 1 day after surgery. Although the ACD had no changes within 2 weeks( all P <0.05), it had been not stable. The changes of the width of the anterior chamber had been stable in the early period after surgery ( all P>0. 05). Conclusion The SL-OCT could impersonality and quantificationally evaluate the anterior segment changes induced by cataract surgery.
