Proportion and characteristic of emmetropia in schoolchildren aged 6-11y: the Shenzhen elementary school eye study.

Aim: To investigate the proportion and characteristic of emmetropia in schoolchildren aged 6-11, especially estimate the normal value of ocular biometric parameters of emmetropia.

Methods: A population-based cross-sectional study was conducted on children aged 6-11y in Shenzhen. Totally, 2386 schoolchildren from two primary schools were involved.

Corneal flap morphological analysis using anterior segment optical coherence tomography in laser in situ keratomileusis with femtosecond lasers versus mechanical microkeratome.

Aim: To assess and compare the flap morphology using anterior segment optical coherence tomography (AS-OCT) in laser in situ keratomileusis (LASIK) with Femto LDV femtosecond lasers versus Hansatome mechanical Microkeratome.

Methods: AS-OCT (Visante) was used to compare 1 month postoperatively the morphology of the flaps created with Femto LDV femtosecond lasers or Hansatome Microkeratome. The intended flap thickness was 110µm and 160µm respectively.

[The efficacy of surgical treatment for encapsulated cystic blebs around the plate after Ahmed glaucoma valve implantation].

Objective: To evaluate the efficacy of surgical treatment for encapsulated cystic blebs around the plate after Ahmed glaucoma valve implantation.

Methods: This was a retrospective observational case series. Thirteen cases with elevated intraocular pressure (IOP) induced by fibrous proliferation around Ahmed valve were retrospectively studied.
