Background: Phacoemulsification with PCIOL decrease the intraocular pressure proportional to
the intraocular pressure seen preoperatively. Various preoperative factors are associated with the
reduction of IOP postoperatively.
Aim: The present study was conducted to assess the cataract surgery phacoemulsification with
PCIOL implantation on intraocular pressure postoperatively and the to assess the relationship
between preoperative ocular parameters including AL ACD, AL, and CCT with IOP change
postoperatively.
Methods:In 262 subjects from both the genders with cataract were treated surgically with
phacoemulsification and PCIOL implantation. Following surgery, all the subjects were followed
up on 1st operative surgical day and 1 month postoperatively for ocular biometric parameters and
reduction in IOP.
Results:BCVA in the study subjects via LogMAR chart was 1-0.76 preoperatively and was 0.16-
0 postoperatively. BCVA using Snellen chart was 72% preoperatively which reduced to 67%
postoperatively. ACD preoperatively was 3.25±0.26 which increased significantly to 3.64±0.29
(p<0.001). Mean IOP in the operated eyes was 13.42±1.98mm Hg which decreased
postoperatively to 11.50±1.68 significantly (p<0.001). It was seen that mean IOP preoperatively
was 13.46±1.96 mmHg which decreased postoperatively to 11.56±1.64 mmHg. The change in
mean IOP at 1 month recall was 1.92±0.59 mmHg. The IOP change at 1 month in percentage
was 14.11%. This change in mean Intraocular pressure was statistically significant with p<0.001.

Comparison of intraocular pressure variance in moderate and high myopia

Abstract: Purpose: Intraocular pressure changes have been, and still is, a topic of discussion.
Increasing myopia has been constantly associated with increasing intraocular pressure.
Myopia has long been identified as a risk factor for open angle glaucoma because of the
changes in optic disc and pressure. Thus, repeated evaluation of all the factors that are related
to changes in IOP levels is important. This can help to figure out the risk factors for open
angle glaucoma in the form of variables that can be proved to be associated with IOP level
changes.
In this study, we will evaluate the intraocular pressure levels between moderate and high
myopia, also taking age and gender in to account
Methods: This is an Observational, hospital-based study conducted on 35 patients presented in
the HAH centenary hospital in the period of 2 months at Delhi. Data confidentiality was
maintained. The detailed demographic details along with ocular findings, systemic health
findings, were collected for analysis. The test used for statistical analysis were Un-paired, 2-
tailed, T-test, Two way ANOVA test. The software MS EXCEL was used.
Results: The hospital-based study conducted at HAH centenary hospital evaluated 35 myopic
patients (70 eyes) in the period of 2 months. Out of 35 patients, 20(57%) were moderate
myopic (-3.00D to <-6.00D) and 15(42%) were highly myopic (-6.00D and more). Range of the
age being 11- 55years. 20(57%) females and 15(42%) males were present in the sample. Only
one patient had IOP level more than 21mmhg and was further examined for glaucoma tests
which came out negative. All the evaluated patients had a C/D ratio less than 0.5
Conclusion: No significant association was found between IOP and myopia along with other
factors such as age and gender. Small sample size and avoiding various others factors such as
ocular biomechanics, corneal thickness, curvature etc. can be the reason for it. Overcoming these
limitations can help confirming a conclusion and give results that would be different and
convincing. The study needs further research time and evaluation.
