 * @class_data: The @class_data member supplied via the #GTypeInfo structure.
 * 
 * A callback function used by the type system to initialize the class
 * of a specific type. This function should initialize all static class
 * members.
 *
 * The initialization process of a class involves:
 * 
 * - Copying common members from the parent class over to the
 *   derived class structure.
 * - Zero initialization of the remaining members not copied
 *   over from the parent class.
 * - Invocation of the GBaseInitFunc() initializers of all parent
 *   types and the class' type.
 * - Invocation of the class' GClassInitFunc() initializer.
 *
 * Since derived classes are partially initialized through a memory copy
 * of the parent class, the general rule is that GBaseInitFunc() and
 * GBaseFinalizeFunc() should take care of necessary reinitialization
 * and release of those class members that were introduced by the type
 * that specified these GBaseInitFunc()/GBaseFinalizeFunc().
 * GClassInitFunc() should only care about initializing static
 * class members, while dynamic class members (such as allocated strings
 * or reference counted resources) are better handled by a GBaseInitFunc()
 * for this type, so proper initialization of the dynamic class members
 * is performed for class initialization of derived types as well.
 *
 * An example may help to correspond the intend of the different class
 * initializers:

 * ]|
 * Initialization of TypeBClass will first cause initialization of
 * TypeAClass (derived classes reference their parent classes, see
 * g_type_class_ref() on this).
 *
 * Initialization of TypeAClass roughly involves zero-initializing its fields,
 * then calling its GBaseInitFunc() type_a_base_class_init() to allocate
 * its dynamic members (dynamic_string), and finally calling its GClassInitFunc()
 * type_a_class_init() to initialize its static members (static_integer).
 * The first step in the initialization process of TypeBClass is then
 * a plain memory copy of the contents of TypeAClass into TypeBClass and 
 * zero-initialization of the remaining fields in TypeBClass.
 * The dynamic members of TypeAClass within TypeBClass now need
 * reinitialization which is performed by calling type_a_base_class_init()
 * with an argument of TypeBClass.
 *
 * After that, the GBaseInitFunc() of TypeBClass, type_b_base_class_init()
 * is called to allocate the dynamic members of TypeBClass (dynamic_gstring),
 * and finally the GClassInitFunc() of TypeBClass, type_b_class_init(),
 * is called to complete the initialization process with the static members
 * (static_float).
 *

 *  look like:

 *  value->data[0].v_pointer = g_strdup ("");
 *  ]|
 * @value_free: Free any old contents that might be left in the
 *  data array of the passed in @value. No resources may
 *  remain allocated through the #GValue contents after
 *  this function returns. E.g. for our above string type:
 *  |[
 *  // only free strings without a specific flag for static storage
 *  if (!(value->data[1].v_uint & G_VALUE_NOCOPY_CONTENTS))
 *    g_free (value->data[0].v_pointer);
 *  ]|
 * @value_copy: @dest_value is a #GValue with zero-filled data section
 *  and @src_value is a properly setup #GValue of same or
 *  derived type.
 *  The purpose of this function is to copy the contents of
 *  @src_value into @dest_value in a way, that even after
 *  @src_value has been freed, the contents of @dest_value
 *  remain valid. String type example:
 *  |[
 *  dest_value->data[0].v_pointer = g_strdup (src_value->data[0].v_pointer);
 *  ]|
 * @value_peek_pointer: If the value contents fit into a pointer, such as objects
 *  or strings, return this pointer, so the caller can peek at
 *  the current contents. To extend on our above string example:
 *  |[
 *  return value->data[0].v_pointer;
 *  ]|
 * @collect_format: A string format describing how to collect the contents of
 *  this value bit-by-bit. Each character in the format represents
 *  an argument to be collected, and the characters themselves indicate
 *  the type of the argument. Currently supported arguments are:
 *  - 'i' - Integers. passed as collect_values[].v_int.
 *  - 'l' - Longs. passed as collect_values[].v_long.
 *  - 'd' - Doubles. passed as collect_values[].v_double.
 *  - 'p' - Pointers. passed as collect_values[].v_pointer.
 *  It should be noted that for variable argument list construction,
 *  ANSI C promotes every type smaller than an integer to an int, and
 *  floats to doubles. So for collection of short int or char, 'i'
 *  needs to be used, and for collection of floats 'd'.
 * @collect_value: The collect_value() function is responsible for converting the
 *  values collected from a variable argument list into contents
 *  suitable for storage in a GValue. This function should setup
 *  @value similar to value_init(); e.g. for a string value that
 *  does not allow %NULL pointers, it needs to either spew an error,
 *  or do an implicit conversion by storing an empty string.
 *  The @value passed in to this function has a zero-filled data
 *  array, so just like for value_init() it is guaranteed to not
 *  contain any old contents that might need freeing.
 *  @n_collect_values is exactly the string length of @collect_format,
 *  and @collect_values is an array of unions #GTypeCValue with
 *  length @n_collect_values, containing the collected values
 *  according to @collect_format.
 *  @collect_flags is an argument provided as a hint by the caller.
 *  It may contain the flag %G_VALUE_NOCOPY_CONTENTS indicating,
 *  that the collected value contents may be considered "static"
 *  for the duration of the @value lifetime.
 *  Thus an extra copy of the contents stored in @collect_values is
 *  not required for assignment to @value.
 *  For our above string example, we continue with:
 *  |[
 *  if (!collect_values[0].v_pointer)
 *    value->data[0].v_pointer = g_strdup ("");
 *  else if (collect_flags & G_VALUE_NOCOPY_CONTENTS)
 *  {
 *    value->data[0].v_pointer = collect_values[0].v_pointer;
 *    // keep a flag for the value_free() implementation to not free this string
 *    value->data[1].v_uint = G_VALUE_NOCOPY_CONTENTS;
 *  }
 *  else
 *    value->data[0].v_pointer = g_strdup (collect_values[0].v_pointer);
 *  return NULL;
 *  ]|
 *  It should be noted, that it is generally a bad idea to follow the
 *  #G_VALUE_NOCOPY_CONTENTS hint for reference counted types. Due to
 *  reentrancy requirements and reference count assertions performed
 *  by the signal emission code, reference counts should always be
 *  incremented for reference counted contents stored in the value->data
 *  array.  To deviate from our string example for a moment, and taking
 *  a look at an exemplary implementation for collect_value() of
 *  #GObject:
 *  |[ 
 *    GObject *object = G_OBJECT (collect_values[0].v_pointer);
 *    g_return_val_if_fail (object != NULL,
 *       g_strdup_printf ("Object passed as invalid NULL pointer"));
 *    // never honour G_VALUE_NOCOPY_CONTENTS for ref-counted types
 *    value->data[0].v_pointer = g_object_ref (object);
 *    return NULL;
 *  ]|
 *  The reference count for valid objects is always incremented,
 *  regardless of @collect_flags. For invalid objects, the example
 *  returns a newly allocated string without altering @value.
 *  Upon success, collect_value() needs to return %NULL. If, however,
 *  an error condition occurred, collect_value() may spew an
 *  error by returning a newly allocated non-%NULL string, giving
 *  a suitable description of the error condition.
 *  The calling code makes no assumptions about the @value
 *  contents being valid upon error returns, @value
 *  is simply thrown away without further freeing. As such, it is
 *  a good idea to not allocate #GValue contents, prior to returning
 *  an error, however, collect_values() is not obliged to return
 *  a correctly setup @value for error returns, simply because
 *  any non-%NULL return is considered a fatal condition so further
 *  program behaviour is undefined.
 * @lcopy_format: Format description of the arguments to collect for @lcopy_value,
 *  analogous to @collect_format. Usually, @lcopy_format string consists
 *  only of 'p's to provide lcopy_value() with pointers to storage locations.
 * @lcopy_value: This function is responsible for storing the @value contents into
 *  arguments passed through a variable argument list which got
 *  collected into @collect_values according to @lcopy_format.
 *  @n_collect_values equals the string length of @lcopy_format,
 *  and @collect_flags may contain %G_VALUE_NOCOPY_CONTENTS.
 *  In contrast to collect_value(), lcopy_value() is obliged to
 *  always properly support %G_VALUE_NOCOPY_CONTENTS.
 *  Similar to collect_value() the function may prematurely abort
 *  by returning a newly allocated string describing an error condition.
 *  To complete the string example:
 *  |[
 *  gchar **string_p = collect_values[0].v_pointer;
 *  g_return_val_if_fail (string_p != NULL,
 *      g_strdup_printf ("string location passed as NULL"));
 *  if (collect_flags & G_VALUE_NOCOPY_CONTENTS)
 *    *string_p = value->data[0].v_pointer;
 *  else
 *    *string_p = g_strdup (value->data[0].v_pointer);
 *  ]|
 *  And an illustrative version of lcopy_value() for
 *  reference-counted types:
 *  |[
 *  GObject **object_p = collect_values[0].v_pointer;
 *  g_return_val_if_fail (object_p != NULL,
 *    g_strdup_printf ("object location passed as NULL"));
 *  if (!value->data[0].v_pointer)
 *    *object_p = NULL;
 *  else if (collect_flags & G_VALUE_NOCOPY_CONTENTS) // always honour
 *    *object_p = value->data[0].v_pointer;
 *  else
 *    *object_p = g_object_ref (value->data[0].v_pointer);
 *  return NULL;

 * @OBJ_NAME: The bare name of the type, in all caps (like `WIDGET`)
 * @ParentName: the name of the parent type, in camel case (like `GtkWidget`)
 *
 * A convenience macro for emitting the usual declarations in the header file for a type which is not (at the
 * present time) intended to be subclassed.
 *
 * You might use it in a header as follows:
 *
 * |[
 * #ifndef _myapp_window_h_
 * #define _myapp_window_h_
 *
 * #include <gtk/gtk.h>
 *
 * #define MY_APP_TYPE_WINDOW my_app_window_get_type ()

 *
 * MyAppWindow *    my_app_window_new    (void);
 *
 * ...
 *
 * #endif
 * ]|
 *
 * This results in the following things happening:
 *
 * - the usual `my_app_window_get_type()` function is declared with a return type of #GType
 *
 * - the `MyAppWindow` type is defined as a `typedef` of `struct _MyAppWindow`.  The struct itself is not
 *   defined and should be defined from the .c file before G_DEFINE_TYPE() is used.
 *
 * - the `MY_APP_WINDOW()` cast is emitted as `static inline` function along with the `MY_APP_IS_WINDOW()` type
 *   checking function
 *
 * - the `MyAppWindowClass` type is defined as a struct containing `GtkWindowClass`.  This is done for the
 *   convenience of the person defining the type and should not be considered to be part of the ABI.  In
 *   particular, without a firm declaration of the instance structure, it is not possible to subclass the type
 *   and therefore the fact that the size of the class structure is exposed is not a concern and it can be
 *   freely changed at any point in the future.
 *
 * - g_autoptr() support being added for your type, based on the type of your parent class
 *
 * You can only use this function if your parent type also supports g_autoptr().
 *
 * Because the type macro (`MY_APP_TYPE_WINDOW` in the above example) is not a callable, you must continue to
 * manually define this as a macro for yourself.
 *
 * The declaration of the `_get_type()` function is the first thing emitted by the macro.  This allows this macro
 * to be used in the usual way with export control and API versioning macros.
 *
 * If you want to declare your own class structure, use G_DECLARE_DERIVABLE_TYPE().
 *
 * If you are writing a library, it is important to note that it is possible to convert a type from using
 * G_DECLARE_FINAL_TYPE() to G_DECLARE_DERIVABLE_TYPE() without breaking API or ABI.  As a precaution, you
 * should therefore use G_DECLARE_FINAL_TYPE() until you are sure that it makes sense for your class to be
 * subclassed.  Once a class structure has been exposed it is not possible to change its size or remove or

Shelley I. Cutler, OD, FAAO, Dipl, FSLS

……is an optometrist who not only performs excellent routine eye care but specializes in difficult to fit and medically necessary contact lenses.

Dr.Cutler graduated from the Pennsylvania College of Optometry (now Salus University) in 1982. Following a Primary Care Residency, also at PCO (1982-1983), she accepted a position at The Wills Eye Hospital (Philadelphia, Pa). As supervisor of the Contact Lens Department, Dr. Cutler was responsible for both the contact lens education (both clinically and didactically) of the Ophthalmology residents and the contact lens care of the clinic patients. She left Will Eye to do specialty contact lens care in the private sector, working closely with Corneal specialists in several ophthalmology practices over the years.

Dr. Cutler was appointed adjunct faculty/consultant at the Pennsylvania College of Optometry in 1985, now Salus University. At various points in time, she has participated as a general clinical instructor in primary care, a contact lens specialty instructor, a contact lens laboratory instructor, co-director and director of the Laboratory portion of the Contact Lens curriculum.

Dr. Cutler became a Fellow of the American Academy of Optometry (F.A.A.O.) in 1987 and in 2002 obtained her Diplomate in Cornea and Contact Lens. In July 2018, she became a Fellow in the Scleral Lens Education Society (FSLS).

Many years ago, Dr. Cutler’s interests had taken her into gaining extra knowledge in nutritional care for the body and eyes. She incorporates this in addressing the issues of lid disease, dry eye and tear film insufficiency as it can be related to overall eye health.

As roads and paths cross over one’s lifetime, from 2007-2014, Dr Cutler worked one day per week in nursing/assisted living homes delivering the necessary general eye care to the Geriatric and Special Needs population who can no longer live on their own because of physical or mental limitations.

In 2012, Dr Cutler chose to focus her energies to what she enjoys the most and started a small, niche specialty practice called Scleral Lens Associates, Inc. (see link below) This is the only practice in the tri- state area (Southeast Pennsylvania, New Jersey and Delaware) that specializes in large diameter Oxygen Permeable Scleral lenses. Scleral Lens Associates, Inc. is dedicated to improving the vision and quality of life for patients with anterior surface disease and irregular corneas! Dr Cutler is 1 of 2 (and the first) certified practitioner of the EYEPRINT PROSTHETIC, an impression molded Scleral device.

Along with seeing patients privately, in January 2020, Dr Cutler joined The Scheie Eye Institute (Penn Presbyterian) and sees patients who need specialty and medically necessary contact lenses.

Dr. Cutler has lectured locally, nationally and internationally on contact lens related topics, has many papers, articles and book chapters published and continues to work as a consultant to Bausch & Lomb in their Specialty Products Division to teach Scleral Lens Education to Optometrists at meetings and in their offices (including hands on Workshops)
