Age-related change in corneal biomechanical parameters in a healthy Caucasian population

Purpose: To determine the effect of aging on corneal biomechanical parameters measured via ocular response analyzer in a homogenous healthy Caucasian population.

Methods: A total of 2039 Caucasian adults were consecutively recruited and divided into seven groups according to decades of age. The difference in mean corneal hysteresis (CH), mean corneal resistance factor (CRF), mean Goldmann-correlated intraocular pressure (IOPg), and mean corneal-compensated IOP (IOPcc) between decades of age were investigated. The strength of the correlations between corneal biomechanical parameters, and between each biomechanical parameter and age were evaluated. The effect of age on each corneal biomechanical parameter was analyzed.

Results: Mean age of the participants (1173 female and 866 male) was 43.30 ± 14.64 years. Mean CH, CRF, IOPcc, and IOPg were 11.49 ± 1.89 mmHg, 11.40 ± 2.30 mmHg, 15.01 ± 3.11 mmHg, and 15.72 ± 3.80 mmHg, respectively. There were significant differences in mean CH, CRF, IOPcc, and IOPg between groups (p < 0.001 for all parameters). There was a significant negative correlation between age and CH (r = –0.067 and p = 0.003), and a significant negative correlation between age and CRF (r = –0.053 and p = 0.017). There was a significant positive correlation between age and IOPg (r = 0.25 and p < 0.001), and between age and IOPcc (r = 0.20 and p < 0.001). Linear regression analysis showed that for every 1-year increase CH decreased 0.011 mmHg, CRF decreased 0.004 mmHg, IOPcc increased 0.053 mmHg, and IOPg increased 0.047 mmHg.

Conclusions: Aging can cause significant changes in corneal biomechanical parameters. Corneal biomechanical parameters were correlated with each other, and each was correlated with aging.

Evaluations of wavefront aberrations and corneal surface regularity in dry eye patients measured with OPD Scan III

AIM: To compare the wavefront aberrations and corneal surface regularity between dry eye (DE) patients and normal subjects and assess its diagnostic performance for DE measured with OPD Scan-III. METHODS: Fifty right eyes of 50 DE patients and 31 right eyes of normal subjects were included. The examinations for ocular surface including logarithm of the minimum angle of resolution best-corrected distance visual acuity (logMAR BCVA) the ocular surface disease index (OSDI), tear film break-up time (TBUT) and corneal fluorescein staining (CFS). OPD Scan-III was used to measure anterior corneal aberrations including total corneal aberrations, high order aberration (HOA), coma, trefoil, spherical aberration (SA), standard deviation of corneal power (SDP), surface regularity index (SRI) and surface asymmetry index (SAI). Statistical analysis were assessed with nonparametric tests and Spearman’s correlations. All parameters were also analyzed for sensitivity, specificity, and receiver operating characteristics (ROC) curves. RESULTS: Wavefront aberrations parameters including total corneal aberrations, HOA, coma, trefoil, and SA in DE group were significantly higher than those in normal group (P<0.001). Corneal surface regularity parameters including SRI and SAI in DE group were significantly higher than both in normal group (P<0.05). All the wavefront aberrations parameters had significant correlations with ocular surface parameters (P<0.05). The logMAR BCVA had positive correlations with SAI and SRI (all P<0.001). CFS scores had positive correlations with SAI and SRI (all P<0.001). All the wavefront aberrations parameters showed good diagnosis sensitivity and specificity, however, the corneal regularity parameters showed only good specificity but poor sensitivity. The cut-off value selected for trefoil in diagnosis DE showed the highest area under the curve (AUC, 0.921) values as compared to the other parameters with sensitivity of 0.955 and specificity of 0.867. CONCLUSION: Wavefront aberrations and corneal surface regularity are increased in DE patients and also correlated with ocular surface parameters. Wavefront aberrations parameters have potential to be indicators to diagnosis and monitor DE.     

Ethnic Variation in Central Corneal Refractive Power and Steep Cornea in Asians

Abstract

Purpose: To describe ethnic differences in the distribution of central corneal refractive power and steep cornea in a multiethnic Asian population.

Methods: A total of 2968 Chinese, 2957 Indian and 2928 Malay participants aged over 40 years were included in this study. Each subject underwent standardized systematic and ocular examinations, interviewer-administered questionnaires, and blood investigations for risk factor assessment. Central corneal refractive power was measured using an autorefractor. Steep cornea was defined as central corneal refractive power exceeding 48 diopters (D) measured by keratometry.

Results: Mean keratometry readings were 43.9?±?1.5?D in Malays, 44.2?±?1.5?D in Indians and 43.9?±?1.5?D in Chinese. The prevalence of steep cornea was 0.6% (95% confidence interval, CI, 0.3–0.9%) in Malays, 1.0% (95% CI 0.7–1.4%) in Indians and 0.5% (95% CI 0.3–0.8%) in Chinese. In multivariate analysis, increasing central corneal refractive power was associated with Indian race, shorter body height, non-smokers, absence of pterygium, shorter axial length, thinner corneas and greater anterior chamber depth, while the presence of steep cornea was significantly associated with Indian race, shorter axial length and thinner corneas.

Conclusions: Indian participants had the steepest corneas among the three major ethnic groups in Singapore. Central corneal refractive power was related to several ocular parameters including anterior chamber depth, axial length and central corneal thickness. These data have important clinical implications for understanding the risk of keratoconus.     

Quantification of Ocular Biomechanics In Ocular Manifestations of Systemic Autoimmune Diseases

Purpose: To quantify biomechanical change associated with autoimmune diseases using Corvis ST deformation data.

Methods: Cross-sectional, observational, case control study of 76 patients with systemic autoimmune disease and 21 control subjects. All patients underwent detailed ophthalmic examination with Corvis-ST (Oculus Optikgerate Gmbh, Germany) measurements for biomechanical properties of the eye.

Corneal deformation and also deformation caused by the extracorneal tissue were recorded. Using a mathematical formula, the three parameters, namely, corneal stiffness (kc), extracorneal tissue stiffness (kg), and extracorneal tissue viscosity (μg), were defined.

Results: The biomechanical analysis showed that kc and μg were significantly lower in patients with systemic autoimmune disease with eye manifestations than control group. However statistically, it was significant in rheumatoid arthritis (RA) patients only.

Conclusion: The new parameters, namely, kc, kg, and μg, can provide a sensitive marker of the ocular activity of the collagen vascular diseases.

Effective Lens Position According to Incision Width in Cataract Surgery Using Phacoemultification and Posterior Chamber Lens Implantation

Purpose: To compare effective lens position (ELP) after phacoemulsification between micro-incision (2.25 mm) and small-incision (2.75 mm) groups.

Methods: Sixty-seven eyes with age-related cataracts were randomly divided into two groups based on the width of the corneal incision (micro-incision [n = 33] and small-incision groups [n = 34]). Participants underwent clear corneal incision phacoemulsification combined with intraocular lens implantation. Uncorrected visual acuity, refractive error, corneal astigmatism, and ELP were measured preoperatively and at 2 months postoperatively. ELP was calculated using the Sheimpflug method.

Results: Postoperative mean visual acuity and refractive error did not differ between the groups (logMAR 0.02 vs. logMAR 0.04, P = 0.108; ?0.30 diopter [D] vs. + 0.07 D, P = 0.339). The postoperative surgically-induced corneal astigmatism was higher in the small-incision group than it was in the micro-incision group, although the difference did not reach statistical significance (+ 0.01 D vs. ?0.36 D, P = 0.063). The mean difference between the pre and postoperative ELP values was significantly higher in the small-incision group than that in the micro-incision group (?0.04 mm vs. ?0.51 mm, P = 0.024).

Conclusions: Although there was no significant difference in postoperative refractive error and corneal astigmatism between the micro- and small-incision phacoemulsification groups, the mean error between pre and postoperative ELP was higher in eyes that underwent phacoemulsification with larger corneal incisions than it was in those that underwent smaller incisions.

Also, the Schirmer 1 (p < 0.001, r = -0.802) and 2 (p < 0.001, r = -0.587) test values showed correlation with the mRSS in dcSSc.

Conclusion: Skin score had clinically significant importance for predicting corneal biomechanical properties and dry eye tests in both lcSSc and dcSSc.     

双眼角膜散光白内障分别植入多焦IOL和散光IOL的临床观察

目的：观察双眼存在不同程度角膜散光的白内障患者分别植入多焦点人工晶状体、散光人工晶状体的临床效果。

方法：观察组为年龄相关性白内障患者20例40眼,术前角膜规则散光一眼1.50～2.50(平均2.15±0.87)D,植入散光晶状体,另一眼角膜散光<1.50D,平均0.78±0.26D,植入多焦点人工晶状体(MIOL)。对照组为同期双眼均植入MIOL的20例40眼年龄相关性白内障患者,规则角膜散光≤1.00D,平均0.62±0.34D。比较术后3mo观察组的散光晶状体眼与MIOL眼的远近裸眼视力及对照组与观察组患者双眼合视的远近裸眼视力。

结果：观察组患者Toric人工晶状体眼的裸眼远、近视力分别为0.81±0.32和0.58±0.27,MIOL眼远、近视力分别为0.76±0.28和0.67±0.24,两眼间差异无统计学意义(t=0.797,P>0.05; t=1.243,P>0.05); 观察组双眼合视的远近视力分别为0.90±0.33和0.79±0.22,对照组双眼合视的远近视力分别为0.92±0.25和0.85±0.28,两者比较差异无统计学意义(t=0.601,P>0.05; t=0.875,P>0.05)。

结论：双眼存在程度不同角膜散光的白内障患者,一眼植入多焦点人工晶状体、另眼植入散光人工晶状体同样可以提高患者术后的脱镜率。
