There were 34 (11.33%) eyes in hypermetrope group, 123 (41%) eyes in emmetrope group and 143 (47.66%) eyes in myope group.
Our patient was a high hypermetrope with thick lenses and occludable angles who had LPIs before Latanoprost had been commenced.
For myopes or low hypermetropes, it is best to choose the CD in the dominant eye and CN in the other, whilst for hypermetropes over +0.75DS, CN lenses should be used for both eyes.
It is thought that the decrease in contrast sensitivity as refraction moves toward hypermetropia may explain why hypermetropes are more prone to amblyopia than myopes.
Out of the total 126 subjects, there were 51 myopic patients 37 emmetropes, and 38 hypermetropes. The mean AA of the three groups has been described in Table 1.
Hypermetropes were affected more (48.2%), followed by myopes (37.7%), then emmetropes (14.1%) (Table 3).
Mean age of hypermetropes was 32.38.33 while other three groups were 23.53.5, 24.53.0, 23.53.0 for low myopia, high myopia and astigmatism respectively.
In our study, 60 patients of the 300 patients were hypermetropes with average corneal thickness of 545 micrometres with SD (34).
It has been shown that hypermetropes exhibit more dramatic changes in anterior segment parameters after cataract surgery.
Monovision laser treatments can be considered for presbyopic myopes and low hypermetropes, where the non-dominant eye is deliberately under-corrected.
Hypermetropes constituted only 1.1% (10/903) of total population - with mean AL of 19.1 mm.
The regression analysis between AXL and CRC showed that an increase of 1 unit in the CRC showed an increase of AXL by 3.03mm with an [R.sup.2] of 0.83, which means that there is a chance of 83.5% to explain this correlation, which is better when compared to the analysis between the reading in myopes and hypermetropes.
(29) In a study by Bosnar et al.,7 PD measured in primary position with Lenstar LS 900 was significantly smaller in hypermetropes of the PEX group (3.93 [+ or -] 0.84 mm) compared to the hypermetropes of the control group of patients (4.30 [+ or -] 0.87 mm) (p=0.03), whereas Doganay et al.26 could not detect any differences between the PEX syndrome, PEX glaucoma and control groups.
(27,28) It may also be higher in hypermetropes. (29) Most readers will know that it is important to record the time of day that IOP is measured.
