[Evaluation of quality of vision in early stage after sub-bowman keratomileusis].

Objective: To assess the quality of vision in the early stage after sub-bowman keratomileusis (SBK) for the correction of moderate and high myopia.

Methods: Retrospective case series. Sixty eight myopic eyes of 35 consecutive patients in Chongqing Medal Eye Institute from May to November 2011 were enrolled in this study.

Anterior segment variations with age and accommodation demonstrated by slit-lamp-adapted optical coherence tomography.

Objective: To investigate anterior segment variations with age and accommodation by slit-lamp-adapted optical coherence tomography (SL-OCT) and determine a safe central vault distance between the implantable contact lens (ICL) and the crystalline lens to avoid contact cataract formation.

Design: Evaluation of diagnostic test or technology.

Participants: Eighty-six patients (126 eyes) under regular review from the Optometry Clinic and Outpatient Department in Zhongshan Ophthalmic Center.

[Slit lamp optical coherence tomography study of anterior segment changes after phacoemulsification and foldable intraocular lens implantation].

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.

[Selection of accurate IOL formula in patients with cataract and high hyperopia].

Objective: To audit intraocular lens (IOL) power predictions for cataract surgery in high hyperopia by comparing the accuracy of different formulae of Haigis, SRKII, Hoffer Q, Hollady, and SRK/T.

Methods: A comparative study was used in 31 eyes with cataract and high hyperopia underwent phacoemulsification and posterior chamber IOL implantation. Eyes were examined with A-scan and IOL Master before the operation.

[An analysis about the safe range of thickness of the residual corneal stroma bed after LASIK].

Objective: To ascertain the safe range of thickness of the residual corneal stroma bed and the length of stable time after LASIK operation.

Methods: Two hundred and twenty seven eyes were randomly selected from cases treated with LASIK in 2000. The posterior curvature of cornea was measured by Obscan II preoperatively and 1, 2, 3, 6 months, 1 year and 2 year postoperatively.
