You will be shown the abstract of a medical clinical trial report. Your task is to extract all the findings from this report into a JSON array. Each finding should contain the following five elements:

- Intervention: The medical intervention being tested. This should be a text span copied from the input passage.
- Comparator: The baseline against which the intervention is being evaluated. This should be a text span copied from the input passage. If no comparator is reported, set to `null`.
- Outcome: The medical outcome whose effect is being measured. This should be a text span copied from the input passage.
- Effect: The effect of the intervention on the outcome, relative to the comparator. The effect should be one of the following three values: ("significantly increased", "significantly decreased", "no significant difference").
- Evidence: The evidence for the effect. This should be a text span copied from the input passage.

Please format your output as a JSON array. Each entry in the output should be an array containing the 5 elements listed above, in the following order: [<intervention>, <comparator>, <outcome>, <effect>, <evidence>].

For example, an output with two findings might read:
```
[["aspirin", "placebo", "headache severity", "significantly decreased", "Mean headache severity was significantly decreased in the aspirin group compared to the placebo group (p < 0.05)."], ["aspirin", "placebo", "weight loss", "no significant difference", "We did not observe any difference in weight loss between the group given aspirin relative to the control group"]]
```

There are 2 finding(s) in the abstract below. Please extract them. Output only the JSON array with these 2 findings. Do not include any additional text.

Abstract:
ABSTRACT.PURPOSE:: To compare two phakic intraocular lenses, Artiflex and STAAR® implantable contact lens (ICL), in high myopia.

ABSTRACT.SETTING:: Isfahan Ophthalmology Clinic, Iran.

ABSTRACT.MATERIALS AND METHODS:: In a randomized, prospective clinical trial study, 40 eyes of 20 patients who came to Isfahan ophthalmology clinic to correct their refractive error were examined. Artiflex was inserted in 20 eyes and ICL in the other 20 eyes. After 1 year, uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), contrast sensitivity, intraocular pressure (IOP), and specular microscopy of corneal endothelium were assessed in both the groups.

ABSTRACT.RESULTS:: In this study, there was no statistical difference between UCVA, BCVA, IOP, cataract incidence, contrast sensitivity, and specular microscopy, 1 year after surgery. 40% of eyes in the Artiflex group developed anterior chamber cell and flare reaction 1 year postoperatively, but no patient in the ICL group developed the same. So, there is obvious difference in the rate of anterior chamber cell and flare reaction between these two groups.

ABSTRACT.CONCLUSION:: These two lenses have similar outcomes except in the incidence rate of anterior chamber cell and flare reaction that is greater in the Artiflex group. So, these two lenses are safe with predictable outcome in treating high myopia.

Findings:
[["STAAR\u00ae implantable contact lens (ICL)", "Artiflex", "UCVA or BCVA", "no significant difference", "there was no statistical difference between UCVA, BCVA, IOP, cataract incidence, contrast sensitivity, and specular microscopy, 1 year after surgery."], ["STAAR\u00ae implantable contact lens (ICL)", "Artiflex", "intraocular pressure (IOP)", "no significant difference", ", there was no statistical difference between UCVA, BCVA, IOP, cataract incidence, contrast sensitivity, and specular microscopy, 1 year after surgery"]]
