Methods: In total, 36 patients (36 eyes) were divided into emmetropia and myopia groups. Twenty seven subjects with good uncorrected distance visual acuity (UCDVA) after surgery were enrolled in the emmetropia group.

Efficacy of phacovitrectomy combined with internal limiting membrane peeling for macular diseases.

Purpose: To observe the efficacy of vitrectomy with internal limiting membrane (ILM) peeling combined with phacoemulsification with intraocular lens (IOL) implantation in the treatment of cataract with co-existing macular diseases.

Methods: A total of 28 cataract patients (28 eyes) with co-existing macular diseases were admitted to Aier Eye Hospital between May 2008 and May 2011. The clinical characteristics were analyzed in this study.

Variation of cataract surgery costs in four different graded providers of China.

Background: China has the largest population of cataract patients in the world. However, the cataract surgery rate per million remains low in China. We carried out a survey on costs of cataract surgery from four different graded providers in China and analyzed differences in cost among these clinics.

[Wavefront analysis in pseudophakic eyes by using allegretto wave analyzer].

Purpose: To analyze the wavefront aberrations of pseudophakic eyes.

Methods: Seventy-eight patients (84 eyes) who have undergone phacoemulsification and Alcon Acrysof SA60AT intraocular lens were divided into 3 groups by the stage of post-operation. Allegretto Wave Analyzer (Wavelight Laser Technologie AG, Germany) implanted into the eyes was applied to analyze the wavefront aberrations.

[Clinical investigation of iris-claw phakic intraocular lens implantation for high myopia].

Objective: To investigate the efficacy and safety of an iris-claw phakic intraocular lens (ICPIOL) implantation for high myopia.

Methods: A consecutive group of 25 eyes in 13 patients with -7.88 to -22.

Ultrasound biomicroscopy of iris-claw phakic intraocular lens implantation.

Purpose: To study in situ the intraocular position of iris-claw phakic intraocular lens (ICPIOL) in myopic eyes using ultrasound biomicroscopy (UBM).

Methods: UBM echograms of the anterior segment were taken preoperatively and 62 to 115 days postoperatively in 6 eyes implanted with the Verisys ICPIOL (AMO). The echograms were assessed for the effect of the ICPIOL on iris tissue.

[The clinical study of stereopsis after bilateral intraocular lens implantation].

Purpose: To observe the stereopsis of senile cataract patients after bilateral intraocular lens (IOL) implantation.

Method: Subjects were divided into two groups: IOL group and normal group. Near stereoacuity with distance and near correction was checked with Randot steretests respectively.

[The posterior chamber phakic intraocular lens implantation for moderate to high myopia].

The posterior chamber phakic intraocular lens implantation (PCPIOLI) was designed to implant an IOL in front of the natural crystalline lens. PCPIOLI offers several advantages, such as potential reversibility, preservation of accommodation and minimal complications. Recent studies suggested that PCPIOLI was a promising alternative procedure for the correction of severe ametropia.

Quantitative measurements of the decentration distance of four kinds of intraocular lens.

Purpose: To investigate a quantitative method to measure decentration distance(DD) and analyze the DD of four kinds of intraocular lenses (IOLs).

Methods: The pseudophakic eye photos were taken under the slit lamp after the IOLs were implanted a year or longer. Then the images were inputted into a computer and the Photoshop software was applied to analyze the DD.

Comparison of the inflammatory reaction to laser photolysis and conventional phacoemulsification.

Purpose: To compare the postoperative inflammatory reaction induced by laser photolysis and conventional phacoemulification.

Methods: Anterior chamber flare and cells were measured preoperatively and 1 day, 1 week, 1 month and 3 months postoperatively in two groups. In group 1, thirty-two eyes underwent laser photolysis.

[The preliminary study of photolysis for cataract surgery].

Objective: To evaluate the safety and efficiency of Dodick-ARC photolysis machine (a kind of Nd:YAG laser system) in the using of cataract surgery.

Methods: 52 eyes of cataract (fifty-two patients) were undergone photolysis with Dodick-ARC laser system and foldable intraocular lenses (IOLs) implantation. The hardness of nuclei was graded as N(1.

Efficacy of 2% lidocaine injection as a topical agent in cataract surgery.

Purpose: To determine whether 2% Lidocaine injection is an effective topical anesthetic agent for non-phaco small incision cataract surgery.

Setting: Charity eye clinic supported by Hellen Keller International.

Methods: One hundred and twenty-five consecutive cataract surgery patients received topical anesthesia with 2% Lidocaine injection solution just 1 and 0.

Comparison of the accuracy of Canon KU-1 IOL measurer and VPLUS A/B scanner in axial length measurement.

Purpose: To evaluate the accuracy of Canon KU-1 IOL measurer (Japanese Canon Company) and VPLUS A/B scanner (French Quantel Company) in axial length (AL) measurement.

Methods: Canon KU-1 IOL measurer and VPLUS A/B scanner were used to measure axial length of human cataractous eyes before cataract surgery. Two hundred and twenty-two cases (433 eyes) were involved.

[A clinical observation of low and negative power intraocular lens implantation].

Objective: To evaluate the clinical effects of the low power and negative power acrylic foldable intraocular lens (Acrysof IOL) implantation.

Methods: Forty patients (56 eyes) received phacoemulsification and above mentioned Acrysof IOL implantation. Intraoperative and postoperative complications, visual acuity and refractive error were observed.

[Tear film changes after phacoemulsification].

Objective: To evaluate tear film changes after phacoemulsification.

Methods: This prospective randomized study involved 68 consecutive patients with age-related cataract (79 eyes) who underwent phacoemulsification. Tear break-up time, Schirmer I test (S I t) value, corneal fluorescein staining, tear film pattern by DR-1 tear interfermetry and the height of tear meniscus were measured preoperatively and 1 day and 2, 7, 14, 30, 180 days postoperatively.
